WHat OS is this (please do read the posting guide)?
The posting guide also asks you to read the help: it says
You will need 'ghostscript': the full path to the executable can
be set by the environment variable 'R_GSCMD'. (If this is unset
the command '"gs"' is used, which will work if it is in your
path.)
If you don't know what that means, please ask your computing support desk
for help.

Dear List,
I am using the bioconductor package Category to do some gene enrichment
analysis, and usually save my KEGGmnplot's using a dev2bitmap command.
This has worked just fine, until suddenly earlier today I got this
error-message:
dev2bitmap("04610_080721.jpg",type="jpeg", height = 10, width = 10,
res = 200)
Error in dev2bitmap("04610_CSF080721.jpg", type = "jpeg", height = 10, :
sorry, 'gs' cannot be found
I don't know what this means, it seems to be something about my
environment.
(From dev2bitmap function:)
gsexe <- Sys.getenv("R_GSCMD")
if (is.null(gsexe) || !nzchar(gsexe)) {
gsexe <- "gs"
rc <- system(paste(shQuote(gsexe), "-help > /dev/null"))
if (rc != 0)
stop("sorry, 'gs' cannot be found")
}
I cant figure out how to fix this. I am not an experienced programmer.
Any help or tips would be greatly appreciated.
Thank you,
Boel
