I just ran this in RStudio and it works fine.
Gender <- c("Female","Female","Male","Male")
Restaurant <- c("Yes","No","Yes","No")
Count <- c(220, 780, 400, 600)
DiningSurvey <- data.frame(Gender, Restaurant, Count)
DiningSurvey
Then I try to run it in Visual Studio and it does nothing at all.
If I go to Test > Run > All Tests, I get this: 'There were successful build errors. Would you like to continue and run tests from the last successful build?' There is no last build and no matter what I try, this doesn't work. IF I hit any function key, including F5, F11, or whatever, this doesn't work!! How can I run R code in Visual Studio? It seems like this should be super-simple, but it is very, very, very difficult.
Thanks.
In general, R in VS works same a R in RStudio. In other words, F5 does not work since R is not a compiled language and does not have predefined entry point. For example, for debugging you set a breakpoint, then attach debugger, then source file and then call the desired function from R interactive window.
To run R in Visual Studio, you need the R Tools for Visual Studio (RTVS) plugin.
You can download this at http://microsoft.github.io/RTVS-docs/
This will turn Visual Studio into a capable client that knows how to deal with R.
Once you've installed RTVS, the easiest way to get started is to create a new R project:
\File\New\Project...\New R Project
This will create a new project with templates for R and Rmd files.
You can send code from an R file to the "R Interactive" window by pressing Ctrl+Enter.

I am new to R and Rstudio and currently trying to figure out a few things that would easen switching too much between the linux-terminal and the file navigating system. As I prefer using the former I would therefore like a method that allows me to open .R files in R studios in-built editor but directly via the linux terminal. I have tried to illustrate what I want on the attached picture. Does this functionality exist? So far I have only been able to execute R scripts via the terminal.
I have trawled through the web trying to find a similar question but they all seem to be related to executing R scripts via the terminal rather than opening them in the Rstudio editor.
I have been using RStudio for a while and recently switched to Visual Studio Code. Until recently, I had no issues opening any files or workspaces, but now when I open some workspaces it seems that R fails to attach to the terminal. I get no errors when I click "R: (not attached)" and ".vsc.attach()" shows up in the terminal like normal but nothing changes. Screenshot of terminal after attempting to attach R to terminal. If I open a new Visual Studio Code window and open a single file, not in a saved workspace, it opens normally and R attaches without any input from me. Screenshot of terminal after opening a new window and file not in a workspace. If I open the same file, not in a saved workspace, and then save the workspace, R is no longer attached and will no longer attach to the terminal. I tried using the fix from this post and added the code from the answer but nothing changed once again.
I started with a fresh install of Visual Studio Code from the website, not the Microsoft store, and did not sign in or sync my settings. I went through the process of setting up R again and used "C:\Program Files\R\R-4.2.1\bin\x64\R.exe" as Rpath and Rterm, which seems to be working so far. I will update my answer if the issue comes back or if I find another solution.
I've just started using R in VS Code and my script is currently stored as an RMD file. I'm pretty sure I can't debug this as there's no RMD debugger for the version of R I'm using, but when I try to run without debugging (from Run > Run without Debugging / Ctrl + F5) it prompts a dialogue box saying 'You don't have an extension for debugging R Markdown.' Surely I don't need a debugger to run without debugging?
I can obviously still run chunks at a time, or by selecting code, so this is more of an annoyance than a serious issue.
I'm using R, Windows 10 and Visual Studio 2015 in my work. I can do calculations well in R console. But as I tried to make a Visual Studio project, I was unable to see the result. My code is the following:
print(2)
I tried to execute in interactive by pressing Ctrl+Enter but I can't see the result. So where do the result should appear?
(I'm assuming you have R Tools from here)
There ought to be an R Interactive window option under the R Tools > Windows menu:
Now the outputs of your R scripts (derived by highlighting some lines and pressing Ctrl-Enter) should go to that window:
If that doesn't work, can you make sure you have the latest version of R Tools? Version 1.0 only just came out recently...
I have a vb.net program which processes some data and user input and then uses R.net to set this information into R objects and run R scripts on these objects.
My problem is that this is hard for me to debug, as the error messages that bubble back up through the Visual Studio debugger about the R scripts are often not helpful.
My latest solution to this is to add
engine.Evaluate("save.image('Scripts/debugging/image.RData')")
into my vb.net code just before the script that has an error. This allows me to load up the objects in my R IDE and check if everything is in the form I expect it to be.
I was wondering if there was a better way to do this? For instance I wonder is it possible to set up the R environment/engine to run a save.image() if an error is encountered automatically?
