[kepler-dev] Problems with pipes, R actors

[Latronico Elizabeth (RTC1)]

Thanks Dan, that fixed it.  R was installed but not on my path.  I used
the Windows installer, but I just installed Kepler as a regular user
instead of as an administrator so probably the installer couldn't update
the path. 

Thanks,
Beth

Hi Latronico,
    The message you show is usually related to either R not being 
installed or not being on the path. The test is to open a command window

and type the command 'R'. You should then see some information about R 
if it is installed and can be found by the OS.
    What OS are you running? R is included in the windows installer but 
not with Mac or Linux versions.
