A colleague designed a script for a bar plot, which I'd like to
export to my directory via the barplot command:
bitmap(file="barplot.tif", type="tifflzw", height=4, width=6.5, res=1250)
Unfortunately, this command produces the following error message:
Error in system(paste(gsexe, "-help"), intern = TRUE, invisible = TRUE) :
'gswin32c.exe' not found
From consulting the archives and the help file, I deduced that I
needed to install Ghostscript, which I did. Subsequent messages in
the archives suggest directing R toward Ghostscript using an
environmental variable, specifically R_GSCMD.
Please do read the help page. You didn't tell us if you added
Ghostscript to your path: if you had done so this would not be needed
(as the help page says).
Unfortunately, I haven't figured out how to use this command. Can
anyone provide assistance?
Sys.setenv(GS_CMD="C:/Program Files/gs/gswin32c.exe")
if what you say below is correct, but
Sys.setenv(GS_CMD="C:/Program Files/gs/bin/gswin32c.exe")
would be more standard for recent versions of Ghostscript.
This is for R version 2.12.0 using Windows XP on a Dell laptop.
OK, but next time please consult the posting guide and give us the
'at a minimum' information asked for there (we need to know if this is
32- or 64-bit Windows on a 32- or 64-bit OS -- and although rare,
64-bit Windows XP does exist).
The path for ghostscript in my program files folder is: C:\Program
Files\gs
Many thanks,

BTW, asking how to set environment variables is covered in the rw-FAQ
and is not an R-devel topic.
