I don't have read.columns() when I start a fresh R session so it looks like it's
not part of the default R installation. Which package does it belong to?
Providing your sessionInfo() is always a good idea as it would at least give
us a clue of where to look for the read.columns() function. Also a small example
(with code) of what you are trying to do would be very useful.
