I cannot figure out what the problem is. You say every column is 
numeric. It's not possible to have a column that contains the value 
"10:100000625:A:G" be numeric.


If you meant to say the every column was character, then the answer 
might be:


colClassvec <- rep("numeric",9)
colClassvec[ c(3,5:7)] <- "character"

NEU <- read.table("gokind.neuropathy.fin", header=T,stringsAsFactors=FALSE, colClasses=colClassvec)
