how I install.packages("ggplot2") - ggplot2

hi I can't install ggplot2 package
my R studio version is 1.2.5033
and I try to install that with these packages but unfortunately don't install :
install.packages("tidyverse")
install.packages("ggplot2")
install.packages("devtools")
devtools::install_github("tidyverse/ggplot2")

Do you receive an error message? Are these tools already installed? Try library(tidyverse). Another area to check is the "Packages" tab inside RStudio (in my version this is the bottom right pane, third tab) - see if those packages are there, and if so, they can be loaded with a check mark.

in vs code the react native suggestions does not showed

I am new in react native when I am typing vs code does not show any suggestions I had tried to re-install the all react-native extension but it does not make any change.
any help, please
Change the language preference in vscode, botton right, and install necessary extensions from vscode extension menu
Suggestions come from the Visual Studio IntelliCode. Go to extensions and install that extension or update if it needs updating. Also install Javacsript tools and if all fails try updating Visual Studio Code, then restart.
thanks for all, I had found the answer by removing vs code and After uninstalling vscode, removed:
1.%UserProfile%.vscode
2.%AppData%\Code
3.%LocalAppData%\Programs\Microsoft VS Code
and after that re-installed and everything is Ok
Just Uninstall VS-Code and then remove the registry by,
click Win+R
type %AppData% and delete all the folders in the code .
reinstall VS-Code, it's working fine for me.

Cannot uninstall a plugin Eclipse Luna or reinstall it

Using the marketplace I installed a plugin (additional axis 2 tools) on a new Luna EE install.
I uninstalled it via the market place, and after a reboot it was still there. Tried this many times.
So I deleted the file manually from the plugins folder and the option was gone.
However, I want to reinstall it (I originally uninstalled it because the dialog kept containing the wrong information and stopping me from building aar file), but when I go to the marketplace it only gives me an option to 'uninstall'.
Ignoring how this is a bit crap, how do I remove this plugin so I can install it again?
I tried downloading the 1.6.2 jar direct from apache but it just gives me an error saying invalid jar repository.
(I know I can generate the service file/aar manually, but I want to do it this way).
thanks.
Go to Help, Instillation Details and try to remove it from installed software and then try to install it again.This works for me whenever I've to uninstall any software.

NuGet Settings
I believe your versions are out of sync. Check your project.json and make sure you are not using different versions. I found that when I had 1 dependency that used 3.0.0-* it upgraded to beta2 from beta1. All of my other dependencies had beta1 actually defined. (Ex: 1.0.0-beta1). If the beta2 assembly shares the same dependency as one of your assemblies using beta1 it will override the older version of the shared assembly that is being used and causes your older version to fail.
You can remove any KRE package by deleting it from c:\Users\<user>\.kre\packages\. If you want to remove KRE and KVM then remove both the .kre folder completely.
However, you don't have to remove it to use a different version. You can either use kvm use <version> or, from VS, select the target framework in the project properties.
I have similar issue and I solved it by following steps.
In NUget Package Manager I selected only one nuget.org ( Disable myget.org by unselecting it)
I goto C:\Users\<>.kre\alias directory. Here you will find default.txt and I replace default.txt value with KRE-CLR-x86.1.0.0-beta1 ( If you downloaded latest version of Kre then this file change and it create problem for VS 2015 Preview)
After this close your solution and open it again. If possible then open as Administrator.
I hope this works for you as well.

Not getting unresolved conflict notification popup alert box in Subversive (SVN in eclipse)

We are a team that just started working with Subversion using Subversive in Eclipse.
I have learned from this guide, (See Resolving Conflicts) that a notification popup alertbox is to be shown when two people make changes to the same file and then try to commit them, resulting in a conflict:
In our installation we are not getting this alertbox. I imagine that it may be a setting that we need to set.
Does anyone know how to get this alert box to be shown?
I add to uninstall and re-install Subclipse. I had both Subclipse and Subversion plugins on Eclipse; I uninstalled both and reinstalled Subclipse and that fixed my problem
