I would suggest reading the help file: read.delim only looks at the

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?
Sure, it's warning you that your file looks like it has 9 columns, but
you said it has 10, and it will not have generated good column names
(but it will have read the file properly).
If you give it 10 names (e.g. using col.names=LETTERS[1:10]) it will be
happy.
