Hi All:
I've been struggling for a while trying to get grImport up and running. I'm on a Windows 7 (home premium 64 bit) machine running R-2.12.2 along with GPL Ghostscript 9.01. I've set my Windows PATH variable to point to the Ghostscript \bin and \lib directories, and I've created the R_GSCMD environment variable pointing to gswin32c.exe. I don't have any experience with Ghostscript, but with the setup described above I can view the postscript file with the following command to the Windows command prompt: gswin32c.exe D:\Sndbx\vasarely.ps However, I can't get the PostScriptTrace() function to work on the same file. Submitting PostScriptTrace("D:/Sndbx/vasarely.ps") gives me the error: Error in PostScriptTrace("D:/Sndbx/vasarely.ps") : status 127 in running command 'gswin32c.exe -q -dBATCH -dNOPAUSE -sDEVICE=pswrite -sOutputFile=C:\Users\Al\AppData\Local\Temp\RtmppPjDAf\file5db99cb -sstdout=vasarely.ps.xml capturevasarely.ps' Your suggestions are much appreciated. Cheers, Al
