Hi all.
I managed to achieve desired with
for (i in 1:length(radky)) {
fname <- paste("coment",i,".txt", sep="")
file.create(fname)
fileCon <- file(fname, "w")
writeLines(test[radky[i] : (radky+pocet)[i]], fileCon)
close(fileCon)
}
For all on Windows - do not use "com1.txt" for file naming (see my
other mail :-)
Cheers
Petr
