after reading some docs I still can not find anything how to escape the "\" string
I know that "\" in files needs to be escaped in order to be read by R. But in Windows if I try to call any shell util I keep getting errors. example:
afile <- "g:\\simulation\\at" works fine with read.table(afile) ...
but if I try sometthing like this: aprogram <- paste( "c:\dir", afile, sep=" " ) system(aprogram) it crashes...
How can I remove the double "\" in the afile ? I know that I need to reconstruct the afile string without the double "\"
Ideas ? or am I missing something ?
Yes, you missed to double it in "c:\dir". Try:
afile <- "g:\\simulation\\at" aprogram <- paste( "c:\\dir", afile, sep=" " ) system(aprogram)
