R help - Mar 2006 - Error with write.table

I'm having this error when I try to output out a gene expression data frame

Error in file(file, ifelse(append, "a", "w")) :
        unable to open connection
In addition: Warning message:
cannot open file 'SAMPLES.txt'

when issuing the command:

write.table(SAMPLES, file = "SAMPLES.txt")


write.table(SAMPLES)

will work fine, but when I specify a location it gives me the above error

The first guess would be that you do not have write permission to the
working directory. If so, either obtain permissions or place the file
in a directory where you can write: Use setwd() or give the full path
to the file.
