Re: [R] R not recognized in command line
It may very well have been an error in the PATH variable. But, I simply deleted the R_HOME variable and also deleted it from the PATH variable. Then I made a new one with the exact same values as before (but it worked this time). R_HOME = C:\Program Files\R\R-2.12.1 path = ...;%R_HOME%\bin\i386;... R is now recognized as a command.

Re: [R] R not recognized in command line
Although it could easily be "user error", I never got Rpy or Rpy2 working an any sort of reliable way. However I did learn a couple of things about the Windows PATH First, (as others have mentioned) it's easiest to modify the PATH through the Windows GUI that comes up when you right click "My Computer", and then you can modify the "Environmental Variables" somewhere. Second, here are examples of the syntax for adding things to the PATH from a DOS command line path = %PATH%;C:\Program Files\R\R-2.12.1\bin path = %PATH%;C:\Rtools\bin path = %PATH%;C:\Rtools\MinGW\bin path = %PATH%;C:\Rtools\perl\bin set R_HOME = C:\Program Files\R\R-2.12.1\ Third, I found this R command useful for checking the path from within R: Sys.getenv()[['PATH']] On Wed, Jan 12, 2011 at 10:43 AM, Aaditya Nanduri wrote: > Im sorry for the late reply. > > The output to echo %PATH% : > > C:\GTK\bin; C:\Program Files\MiKTeX 2.8\miktex\bin ;C:\Windows\system32 > ;C:\Windows > ;C:\Windows\System32\Wbem; C:\Windows\System32\WindowsPowerShell\v1.0\; > C:\Program > Files\MATLAB\R2008a\bin; C:\Program Files\MATLAB\R2008a\bin\win32; > C:\Program Fil > es\QuickTime\QTSystem\; C:\MinGW\bin;c:\Program Files\Microsoft SQL > Server\100\To > ols\Binn\; c:\Program Files\Microsoft SQL Server\100\DTS\Binn\; C:\Program > Files\ > R\R-2.12.1\bin\; C:\Program Files\Python27; C:\Program Files\SSH > Communications Security\SSH Secure Shell;C:\Python26;C:\Python26\Scripts > > 2011/1/8 Uwe Ligges > > > OK, then let's see if you managed to change the PATH or let is see what > is > > incorrect there.

Re: [R] R not recognized in command line
Aaditya, I was also having some trouble using RPy2 (spoiler alert: I gave up!) to write a GUI for some R scripts I've written. I found a workaround to integrate R and python without using that module. The idea is: 1. Write R scripts you want to use in python. I have a file with all of the functions I'll need to use. 2. Write python code that writes R code (according to whatever inputs you want...) calling the functions in your script. For example, if the R function I wanted to use was "sum", I'd have users input two numbers in python, and have python create the string "sum(867, 5309)" 3. Open the file with the Rscript using python, and add "sum(867, 5309)" to the end of it. 4. Create the string t = "cd C:\Program Files\R\R-2.11.0\bin&Rscript sum.r" in python, where "sum.r" is a file with the "sum" function, to which we added the string "sum(867, 5309)" using python and "C:\...\bin" is whatever directory your R installation is in. 5. Finally, open the shell as a subprocess using python and send "t" to the shell. This method works if you don't need to see the output of the R script in the python console. If you really want to see that, have R write the output into some file that python can open and open that with python script! I did all this without any experience with python (I'm alright with R), so you may even find some shortcuts.

Note it is also possible to make global changes using the powershell
by setting the user to "Machine".

Re: [R] R not recognized in command line
Hi Aaditya, I assume you are running some variant of Windows and by the "prompt in DOS" you are using cmd.exe. Perhaps you are already, but from your examples it looks like either A) you are not in the same directory as R or B) are not adding the path to R in the command. For example, on Windows I always install R under C:\R\ so for me inside cmd.exe: C:\directory> C:\R\R-devel\bin\x64\R [[[R starts here]]] alternately you could switch directories over and then just type "R" at the console: C:\directory> cd C:\R\R-devel\bin\x64\ C:\R\R-devel\bin\x64> R [[[R starts here]]] or since you have set the environment variables: C:\directory> %R_HOME%\bin\x64\R [[[R starts here]]] Alternately, edit the PATH environment variable in Windows and add the path to R (i.e., R_HOME\bin\i386\ or whatever it is for you), and you should be able to just enter "R" at the command prompt and have it start.

[R] R not recognized in command line
Hello all, I recently installed rpy2 so that I could use R through Python. However, R was not recognized in the command line. So I decided to add it to the PATH variables. But it just doesnt work And what I mean by it doesnt work is : No matter what I type at the prompt in DOS- be it R, Rcmd, R CMD, Rscript- it is not recognized as a command. Path variables used : 1. %R_HOME% --> C:\Program Files\R\R 2.12.1\ 2. %R_HOME%\bin 3. %R_HOME%\bin\i386 4. Some Batchscripts I found online that recognize the R.exe in \bin\i386 but only if I run the batch file...its not natively recognized (if I were to type 'R' at the prompt in DOS, its not recognized) I would appreciate any help in this matter. Or should I do something else so that I can try rpy2?
