I am trying to create random numbers in within normal distribution given random probabilities in a range. My code is the following:
Range(Cells(2, 1), Cells(RandomNumbers + 1, 1)) = WorksheetFunction.Norm_S_Inv(Rnd)
Where RandomNumbers is just a value in another cell. The problem is that if RandomNumbers is equal to, lets say, 10 then VBA fills the same random number in all 10 cells. How do I make every number different in every cell?
Make it a loop:
Dim cell as Range
For Each cell In Range(Cells(2, 1), Cells(RandomNumbers + 1, 1))
cell.Value = WorksheetFunction.Norm_S_Inv(Rnd)
Next

At the beginning of my macro I need to have a certain range of cells in column R filled with the numbers 0, 1, 2, 3, 4... up to 40. Hence 0 to 40 in increments of 1. This is the simple code I propose to use but what formula after the = sign can I use to do this?
With ThisWorkbook.Sheets("Sheet1")
.Range("R17:R57") =
End With
You can use a for loop, which will increment a variable by 1. For example,
For i = 0 To 39
Worksheets("Sheet1").Cells(i+17, 18).Value = i
Next i
This will fill R17 through R57 with values 0 through 40.
I'm having trouble with a specific process.
In column H, there are a bunch of different numbers. I'm looking for a loop, that for each newfound value in the column, counts how many times the value occur in that column, and put's the counted value in the next worksheet "Statistik".
I do have a solution were I make a code for each individual number in the column, but i'm looking for a loop, since there are 28 different values ind that column.

Does anyone have a bright solution for my problem?
Thanks in advance.
You need to use COUNTIF. Either as a formula or in your VBA code (Application.CountIf()).
In your case =COUNTIF(H:H, [UNIQUE_VALUE]) where unique value is the value you want to extract. To get unique values you have two options. One is to copy unique values from H:H to your Statistik sheet as follows:
Click the Data Ribbon Menu
Select the Advanced Button in the Sort & Filter section
Fill in the dialog Box, Copy to another location, List range H:H, Copy to Some column in Statistik sheet* making sure you tick **Unique records only
Other option to get unique values is detailed here https://exceljet.net/formula/extract-unique-items-from-a-list
For more information about COUNTIF

You could use a dictionary to output only 1 key and value
Option Explicit
Public Sub GetCount()
Dim dict As Object
Set dict = CreateObject("Scripting.Dictionary")
With Worksheets("Sheet1") 'change as appropriate
Dim arr(), i As Long
arr = Intersect(.Columns("H"), .UsedRange) '<=== Specify exact range in H to loop over if you want including header
For i = LBound(arr, 1) + 1 To UBound(arr, 1) 'assuming header to ignore otherwise start at 1
If Not dict.exists(arr(i, 1)) Then
dict.Add arr(i, 1), 1 '<==== if value not seen before add to dictionary with value of 1
Else
dict(arr(i, 1)) = dict(arr(i, 1)) + 1 ' <====== if seen before add 1 to the existing count
End If
Next i
End With
With Worksheets("Statistik")
.Range("A1") = "StudyBoard_ID"
.Range("B1") = "Count"
.Range("A2").Resize(dict.Count, 1) = Application.Transpose(dict.Keys)
.Range("B2").Resize(dict.Count, 1) = Application.Transpose(dict.Items)
End With
End Sub
I want the cell to number itself in an incremental order depending upon the filters. I found the easiest way is to check for the above Row if it is hidden or not then number itself from 1 if hidden and previous cell value+1 if not hidden.
I've tried to achieve this using the Formula
=IF(COUNTA(ADDR)>SUBTOTAL(103, ADDR), 1, ADDR+1)
Where ADDR is defined as follows:
=ADDRESS(ROW()-1,COLUMN(), 4, TRUE)
SUBTOTAL function returns #VALUE as it cannot contain 3-D References.
Tried replacing SUBTOTAL() function with AGGREGATE(), same issue.
Tried to use VALUE() function to convert the ADDR string to value.
I tried to use VBA
Public Function IsHid(i As Integer)
Dim re As Range, x As Integer
Set re = Range("A" & i)
If re.EntireRow.Hidden Then
Set re = Range("A" & i + 1)
re = 1
Else
x = re.Value + 1
Set re = Range("A" & i + 1)
re = x
End If
End Function
The above function returns #VALUE.
The below function also returns #VALUE.
Public Function IsHid(i As Integer)
If Excel.ThisWorkbook.ActiveSheet.Rows(i).Hidden Then
Cells(i + 1, 1).Value = 1
Else
Cells(i + 1, 1).Value = Cells(i, 1).Value + 1
End If
End Function
Very much appreciated if this functionality can be obtained by means of FORMULAS rather than the VBA
Use Subtotal combined with Count(A):
=SUBTOTAL(3,B$2:B2) and paste down.
This can be in column A and will number only visible rows when you filter on B, C, etc.
You might want to take a look here as well, for additional explanation.
Edit:
Let's say you have Sheet1 and you fill up Range A:G. In column A you want the numbering described in the question. Then Range A1 will hold a header (e.g. FilteredID) and Range B:G will hold your other values.
In range A2 all the way down, you put the formula =Subtotal(3, B$2:B2), in Range A3 this will be =Subtotal(3, B$2:B3), in A4 =Subtotal(3, B$2:B4), etc.
Now, when you filter on column B, C, D etc. so you'll have invisible rows, the numbering in column A will show the visible Row number.
For example, assuming you want to start numbering in row 2 and in column A and you have Excel 2010 or later:
=AGGREGATE(4,5,A$1:A1)+1
Just adjust the start cell as required.
For some reason, even when I select a column, right click, and format the cells to be numbers, I still get an alert with a green corner in the cell that says that it's a number stored as text. I then highlight the range, click the exclamation point in the yellow box, and convert the range to numbers.
The problem is that I have to do this for hundreds of ranges.
How can I make a macro to highlight a range (e.g. XP2:XP2700) in every 9th column, and convert the entire range to numbers?
This is a follow-up to the OP's previous question, which, I answered.
Load the data into an array typecast it into a number then write it back over the original range.
Sub ConvertToNumber()
Dim x As Long, y As Long
Dim Data
With Worksheets("CPR Test 2013-2015")
For y = 1 To 1582 Step 9
Data = .Cells(2, y).Resize(2699, 1).Value
For x = 1 To UBound(Data, 1)
If IsNumeric(Data(x, 1)) And Not IsEmpty(Data(x, 1)) Then
Data(x, 1) = CDbl(Data(x, 1))
End If
Next
.Cells(2, y).Resize(2699, 1).Value = Data
Next
End With
End Sub
I want to copy the cells "A2:A" & patientprofiles + 1 and paste them in the first unused row in column D (i.e., there should be no blank cells between what's already in column D and what I want to paste there, but I also don't want to paste over what's already there). I then want to repeat this process a user-defined number of times (this variable will be called g1_observations). I then want to copy the cells "A" & patientprofiles + 2 & ":A" & 2 * patientprofiles + 1 to the new last used row in column D (i.e., taking into account that I've just pasted patientprofiles number of cells g1_observations number of times at the bottom of column D. I want to continue repeating this process a user-defined number of times (this number of times is defined by the variable numberofgrids).
For example: imagine that the user has defined that there will be three grids. Grid 1 will have 2 observations, Grid 2 will have 3 observations, and Grid 3 will have 4 observations. Also imagine that patientprofiles has been set to 40.
If this is the case, there will already be values in cells D1:D121, so I want to begin pasting in D122. I want to paste the cells A2:A41 (40 cells because patientprofiles = 40) to cells D122:D161; I want to paste the cells A42:A81 to cells D162:D201 and again to D:202:D241; and I want to paste cells A82:A121 to cells D242:D281, again to cells D282:D321, and again to cells D322:D361. I'm pasting each "grid" one less time than the number of observations for that grid, because the first group of observations for all grids is what's contained in cells D2:D121. End example
I'm pretty sure I need to use a nested For...Next loop in order to do this, but I'm having trouble with both the inner and outer loop. I think the outer loop should go something like this:
Dim i as long
For i = 0 to numberofgrids - 1
[insert inner loop here]
Next
As far as the inner loop goes, I'm not really sure what I'm doing because it keeps pasting over itself when I am pasting from two grids. The current code I have uses repeated For...Next loops and doesn't work:
Dim myLastRow as Integer
myLastRow = Worksheets("Work").UsedRange.Rows.Count
Dim j as Long
For j = 1 To g1_observations - 1
If j = 1 Then
Range(Cells(2, 1), Cells((patientprofiles + 1), 1)).Copy _
Destination:=Worksheets("Work").Cells(j * myLastRow + 1, 4)
ElseIf j > 1 Then
Range(Cells(2, 1), Cells((patientprofiles + 1), 1)).Copy _
Destination:=Worksheets("Work").Cells((j + 1) * (myLastRow / 2) + 1, 4)
Else: Range("A1").Select
End If
Next
For j = 1 To g2_observations - 1
If j = 1 Then
Range(Cells(patientprofiles + 2, 1), Cells((2 * patientprofiles + 1), 1)).Copy _
Destination:=Worksheets("Work").Cells(j * myLastRow + 1, 4)
ElseIf b > 1 Then
Range(Cells(patientprofiles + 2, 1), Cells((2 * patientprofiles + 1), 1)).Copy _
Destination:=Worksheets("Work").Cells((b + 1) * (myLastRow / 2) + 1, 4)
Else: Range("A1").Select
End If
Next
It pastes over itself, and sometimes it skips lines. I can't really figure out how to reconcile myLastRow with a loop.
I think the inner loop should probably start off something like this:
Dim j as Long
For j = 0 to gj_observations - 1
Range(Cells(j * XXX + 2, 1), Cells((j + 1) * patientprofiles + 1).Copy _
Destination:=Worksheets("Work").Cells(myLastRow * j + 1) , 4
but I'm having difficulty because the variables are called g1_observations, g2_observations, g3_observations, etc., all the way up to g10_observations, and obviously gj_observations won't work. I want to loop on the number between "g" and "_", but I don't know how to get VBA to read variables that way, or if that's possible at all.
Can anyone help me out here? My mind is spinning from trying to understand the concept of loops, especially with different variables at each level.
Also, side question, how do you tell VBA to do nothing in an If statement? I currently have it selecting A1 by writing Else: Range("A1").Select, but I'm sure there's a better way of doing it.
When you're writing macros, it's a better practice to work with ranges and avoid manipulating cells one at a time in a loop. Your macro will run much faster and the code will be clearer.
If you want to create a set of variables that you can access by number, you would use something called an array. This is a pretty fundamental concept that exists in almost every programming language, so I'll refer you to MSDN or your favorite VBA language reference guide for more details.
Dim ws As Worksheet
Dim lr As Long ' Last Row
Dim szpp As Long ' Size (rows) patient profiles
Dim szgobsrv(2) As Long ' Size (rows) observation groups
Dim i As Long
Dim j As Long
Dim SourceCells As Range
Dim TargetCell As Range
Set ws = Sheets("Work")
szpp = 40
szgobsrv(0) = 1
szgobsrv(1) = 2
szgobsrv(2) = 3
For i = 0 To UBound(szgobsrv)
lr = ws.UsedRange.Row + ws.UsedRange.Rows.Count - 1
' copy the patient profile cells multiple times depending on group size
For j = 0 To szgobsrv(i) - 1
Set SourceCells = ws.[A2].Offset(i * szpp).Resize(szpp)
Set TargetCell = ws.[D1].Offset(lr + j * szpp)
SourceCells.Copy TargetCell
Next
Next
Note the usage of the Resize and Offset methods. These are helpful Range methods that can change the size and position of a range by a fixed amount.
The main problem you are having with values being over written is that youre not using Offset.
Another important thing to remember about nested loops is that the nested loop runs i times per loop of the upper level loop. I am thinking that nested loops here might not be good for you. You could probably just make them all independent loops?
If you want to loop to the number contained within the variable you might want to set that variable equal to a number.
example:
g2_observations =2
For j = 1 To g2_observations - 1
Aside from this I am actuall yhaving difficulty understanding what you need, but hopefully this helps?
numberofgrids = input
i = 1 to numberofgrids
gridCount = gridCount + 1
'Loop Stuff
Case Select gridCount
Case is = 1
'logic
Case is = 2
'logic
Etc etc
End Select
If numberofgrids = gridCount Then
Exit For
End If
Next i
