问题
I know there are a lot of questions regarding this issue but I've tried everything and I think I just don't understand how the command line works in windows. I have a file saved in a folder on my desktop, let's say:
C:\Users\abika_000\Desktop\R models\myfile.R
Here is the directory to my R/bin or Rscript/bin:
C:\Program Files\R\R-3.1.0\bin
I want to run this code using the cmd prompt. How would I go about doing this?
I've tried this solution from the question below but I just keep getting errors no matter what I do:
Run R script from command line
What I entered:
> R CMD BATCH C:\Users\abika_000\Desktop\R models\myfile.R
> Rscript C:\Users\abika_000\Desktop\R models\myfile.R
The errors I get are:
'R' is not recognized as an internal or external command, operable program or batch file
'Rscript' is not recognized as an internal or external command, operable program or batch file
EDIT::
Credit to splendour and Phil. I wound up fixing it by entering:
> "C:\Program Files\R\R-3.1.0\bin\"R CMD BATCH "C:\Users\abika_000\Desktop\R models\myfile.R"
I apologize for the poor question. I just wasn't sure how to use the cmd prompt /directories in trying to use R CMD BATCH or Rscript
回答1:
I think step 1, if you haven't already done it, is to use a UNIX-y shell emulator, such as Cygwin. Then, assuming it's available on Windows (as it is on Linux/OSX), you can use the wrapper program Rscript.
Or, if you have a UNIX-y shell emulator, you can always pipe input straight into R
, e.g.:
R --no-save --no-restore < your_script.R
回答2:
The executables for R
have not been added to your environmental variable PATH
. The error you are receiving is CMD complaining that it cannot recognize R
as an executable.
Both R
and Rscript
exists under Windows.
From the CMD, write
echo %PATH%
Did you see the path where R is install there? Probably not.
Where is R installed? I'm guessing something like C:\Program Files (x64)\R\R-3.1.2
Follow this link for adding a path to PATH
: http://www.computerhope.com/issues/ch000549.htm
The path you want to add is not the location where R is installed, but a subdir. Either add C:\Program Files (x64)\R\R-3.1.2\bin
or C:\Program Files (x64)\R\R-3.1.2\bin\x64
.
Restart a command prompt, and try to start R
from the command line (just type R
).
