In the current version (2.13.1) textConnection is much slower if you have a
large file (>1 lines) than using a temporary output file. Try timing a
script using the two different approachs to get an appreciation for the
difference.

just read in the file using the tab as the separator. if this is a problem
because a tab might appear by itself, then use readLines to read in the file,
gsub to replace the blank/tab with a new separator, writeLines to write out to
a temporary and then read in from the temporary file.

Hi all,
I have a list that I got from a web page that I would like to crunch.
Unfortunately, the list has some unusual separators in it. I believe
the columns are separated by 1 space and 1 tab. I tried to insert
this into the read.table( ..., sep=" \t", ...) but got an error that
said something
