如何设置conda安装的R，以便与RStudio一起使用？

I've been trying to set up my R using conda (eventually to use with Beaker Notebook) and I want to be able to use RStudio with my conda-installed version of R.

My method of installing R:

I ran that version of R (I only installed this version)

Running R in Jupyter is kind of buggy. For example, when it outputs errors, it outputs to stdout and splits every character in the string with a linebreak. I want to use RStudio but I don't want to install another version of R.

How can I route my conda version of R into RStudio?

Here's my .bash_profile not sure if this will be useful:

I've been trying to follow these tutorials but I am lost. I'm really not too familiar with environment variables and such things.

(1) https://support.rstudio.com/hc/en-us/community/posts/207830688-Using-RStudio-with-conda

(2) Launch mac eclipse with environment variables set

when I looked for my R it directed me to:

but the directions from (1) is using this path which is very confusing:

I tried doing what this guy did and added this to my .bash_profile but it didn't work. I even made a .bashrc but it still didn't work (I sourced both after I added the lines)

export RSTUDIO_WHICH_R=/Users/jespinoz/anaconda/bin/R

How to tell RStudio to use R version from Anaconda

Unfortunately, anaconda has no tutorial for this in https://docs.continuum.io/anaconda/ide_integration

So long as which R shows up a working R interpreter (which it should do if you have installed the r package from conda and activated your environment) then launching rstudio from that same environment should pick it up just fine.

For a test, on ArchLinux, I built and installed: https://aur.archlinux.org/packages/rstudio-desktop-git/

.. then force removed the R interpreter (pacman -Rdd r), then installed r from conda (conda install -c r r) and it worked fine. I then closed my terminal and opened a new one (so that the correct conda environment was not activated and successfully launched RStudio with the following command: RSTUDIO_WHICH_R=/home/ray/r_3_3_1-x64-3.5/bin/R rstudio

I think the crux is to launch RStudio from the right environment? Your ~/.bash_profile and ~/.bashrc are only sourced when you run bash. For environment variables to be set so that the your desktop environment knows about them, on Linux, you should put them in ~/.profile or else in /etc/pam.d (you may need to logout or shutdown after making those changes) and on OS X, you should check out https://apple.stackexchange.com/q/57385

See https://anaconda.org/r/rstudio:

Then from command line:

(It is how I installed it and it works.)

An addition to what @Ray Donnelly said above. Basically, it has to be executed from the correct environment (i.e. run it from the terminal).

You can either:

(A) Put this in your ~/.bash_profile export RSTUDIO_WHICH_R=/Users/[yourusername]/anaconda/bin/R (if youre using conda but you could put any R path)

(B) then type this in the terminal after it's been sourced (either restart terminal or do source .bash_profile): open -a RStudio That should work.

or you can do what I did:

(A) open up automator (sorry if you're not on a mac; this will only work on mac)

(B) use a Run Shell Script

(C) then delete cat that's already in there and put in: export RSTUDIO_WHICH_R=/Users/[yourusername]/anaconda/bin/R open -a RStudio

(D) Save it as something like run_rstudio.app then just run that and it should work:
