Duncan, I have tried to pass colClasses but R complains: test <- read.delim("mypaths4.txt", sep="|", quote=NULL, header=F, colClasses=c("character","character","character","character","character","character","character","character","character","character"), fill=TRUE) Warning message: In read.table(file = file, header = header, sep = sep, quote = quote, : cols = 9 != length(data) = 10 once again this is with data: A|B|C|D A|B|C|D|E|F A|B|C|D|E A|B|C|D|E|F|G|H|I A|B|C|D A|B|C|D|E|F|G|H|I|J Any idea?
