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.
Another question is there any more memory efficient than read.table way to
create a data frame from a table?
I use:
> version
_
platform Windows
arch x86
os Win32
system x86, Win32
status
major 1
minor 1.1
year 2000
month August
day 15
language R
>
And this is the shortcut to run R:
D:\R\rw1011\bin\Rgui.exe --nsize=2800k --vsize=100M
Thank you,
Vadim
