I'm new on shiny and flexdashboard.With flexdashboard I've written a .Rmd file to make a nice shiny application (I'm just a statistician).
I want to export some calculations (by a download button)in a report with a pdf file. In shiny examples, I need again to create another Rmd file, as an example of report.Rmd. I can open my application in the browser, and i'm successful to download a pdf file. But it's not working online (with shinyapps.io). I have two files with .rmd extension, and another one with .r extensions(my functions). Can it be the problem of the two.rmd?Do you Have any idea or example working?
thanks a lot in advance
It may be that the server is expecting the function files (*.R) in a certain folder and you are uploading it to another (or in the base folder).
I believe the convention is to put source files into a sub-folder called "R": /R/
If that doesn't work then try \www\. This is where icons are normally sourced from.

I want to add a link to some text within a PDF that will bring up another PDF that is located in the same folder. I wish to use relative addressing so that the PDF suite is transportable to other users and computers. I wish this to work on Linux and Macs.
LibreOffice Draw, despite promises, writes out the link address as a full path. Thus if taken to another computer with another user the link fails to work.
I tried manually editing the PDF files using vi and altered the link syntax so;
<</Type/Annot/Subtype/Link/Border[0 0 0]/Rect[940.9 480.3 1200.7 507.9]/A<</Type/Action/S/URI/URI(Content/Information.pdf)>>
where the target file, "Information.pdf" is in a subdirectory "Contents".
On Linux using Document Viewer, it works! On an Apple, Preview (a PDF viewer) interprets the target file needs to be opened by some application. Adobe Reader doesn't like this syntax either. I tried prefixing the filename with the keyword "file:" which works for a full path but not with relative addressing.
Does anyone know what syntax might work for me
Editing a PDF you can select text and add a hyperlink using LibreOffice Draw. It is then possible to edit the PDF file with a text editor such as vi.
To find the line with the link search for the filename of the target. One problem is that LibreOffice insists in using a fully qualified domain name to locate the file and this won't work after the file is moved, say to another computer. The unedited line should be similar to;
<</Type/Annot/Subtype/Link/Border[0 0 0]/Rect[940.9 480.3 1200.7 507.9]/A<</Type/Action/S/URI/URI(File:<fullpathname>/Content/Information.pdf)>>
Where Content/Information.pdf is the link target in the same directory as the linking pdf. This line should be changed to
<</Type/Annot/Subtype/Link/Border[0 0 0]/Rect[940.9 480.3 1200.7 507.9]/A<</Type/Action/S /Launch/F(Content/Information.pdf)>>
This works on Unix and MacOs
I am running Excel version 16.45 on Mac.
I have created a .iqy and saved it in the Queries directory alongside certain templates which were already there.
I go to Data/Get External Data/Run Web Queries. While the templates are accessible, my file is visible but greyed out (same thing happens if I save the file in a different directory).
Would anyone be able to help?
According to your information, I would like to confirm whether the issue occurs when you follow the steps as below:
1.Create a Word file, paste the web URL.
2.Save the Word as .iqy with .txt format.
3.Choose MS-DOS as coding.
4.Create an Excel file and click "Data >Get External Data >Run Web Query (Or Run Saved Query) " of the Bar
I was able to address the issue as follows.
When navigating to the relevant directory with Finder, the '.iqy' file appears to be appropriately named (as per Image 1).
In fact, if you reach the file in Terminal, the file is saved as '.iqy.txt'.
So all I had to do is rename the file, simply removing the '.txt' string at the end.
Screen you see when navigating in Finder
I have a folder of PDF files, what I want to do is build a small app with directional arrows that when pressed should upload the next PDF file from the uploaded/Selected folder.
I have tried uploading single PDF and I was able to view it, but I'm unable to find any good resource on how to upload a whole directory inside the application for me to not upload each PDF every single time.
I should be able to change my current opened PDF to the next one inside the folder.
The way to do this in Vue is as follows:
Make a input field and attach the event "v-on:input" with the function that will be called when the input is selected.
Don't forget to add "webkitdirectory mozdirectory" for firefox and chrome browsers.
Inside the function fetch the input query via "document.querySelectorAll('input');". The information of files will be inside files object.
Please, help me and tell me what am I missing.
My goal is to display simple PDF file (stored locally for example) in the WebView control. Can I bind path of the file to the Source property of the WebView? Or what is the correct way to show PDF in UWP?
P.S. and if the only option is to do like here - how must I add pdf.js to my project??
My goal is to display simple PDF file (stored locally for example) in the WebView control.
If you want to display pdf in WebView control, then the methods in Display a Local PDF File in a WebView is most like the only way to solve your problem.
You can follow the steps in the xamarin official document, and here are some additional tips we need to pay attention to:
After downloading pdfjs, for UWP app, you need to copy the entire folder into the Assets folder, make sure that the folder is named "pdfjs", otherwise you will need to modify the code to change the path.
Your .pdf file should be stored into the Content folder under the Assets folder, it means you will need to create a new folder named "Content" under Assets and copy your .pdf file into this folder. Otherwise, you will also need to modify the code to change the path.
After copying your .pdf file into the "Content" folder, don't forget to change the Build Action of this file to Content like this:
Or what is the correct way to show PDF in UWP?
In uwp app, you can use Image to show PDF file, you can refer to the official PDF document sample. But I don't know if PDF can be displayed as Image in Android and IOS apps, since you're developing a cross-platform project, I think it's better to use the built-in method to solve such problem.
If a demo for xamarin UWP is needed, you can leave a comment, I will upload my demo later.
I'm supposed to develop a mobile app for moodle using android on titanium studio. And I have been searching for days for any helpful article on how to get a file chooser dialog to work on android. Most of the tutes offer image upload but I need to upload .pdf and zip files from mobile. I have already tried fileChooserDialog() and folderChooseDialog() to no avail. Help please?
There isn't a file chooser out of the box, as apps usually send files to each other internally. You can roll your own using ListViews though easily..
Build a list of all the files you're interested in. (https://docs.appcelerator.com/platform/latest/#!/api/Titanium.Filesystem.File-method-getDirectoryListing)
Loop through the list omitting any file types you don't want and build the list
When the user selects a file capture the click event and upload that file.
Style however you want..
