read.table memory requirements

Hi,

I tried to read in a big table (1.4M rows, 4 fields each) using read.table()
and ran out of 'cons' memory with the following message:
Error: cons memory (2800000 cells) exhausted

Could someone please explain how to guess required nsize? My understanding
of help(Memory) is that 'cons' memory should not be a limitation unless you
create many "language" objects.

One simple and general solution is to upgrade to 1.2.0, where memory size
is adjusted automatically.

I don't think we have ever worked out the exact memory requirements of
read.table.
