I am using read.table("data.txt", sep="\t") to read in a tab-limited text

but to no avail.
Set the column classes (using the colClasses argument). It is guessing
numeric, but clearly that's not true.
I don't think any recent version of R (e.g. 2.7.1 and later) does that,
although some earlier versions did on some platforms.
So an even better solution is to update the R involved (as the posting
guide asked...).
