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?

Brian
