I was going to suggest using readBin, but there seems to be a bug:

> con <- file('c:/test.txt','rb')
> readBin(con,'c',15,1)
stack imbalance in internal readBin, 9 then 8stack imbalance in
.Internal, 8 then 7
stack imbalance in {, 6 then 5
NULL
Error: unprotect(): stack imbalance

This was in today's r-devel build for Windows, but the bug also shows
up in 1.7.1.  I'll look into it.
