R-beta: read.table and large datasets
I find that read.table cannot handle large datasets. Suppose data is a
40000 x 6 dataset
R -v 100
x_read.table("data") gives
Error: memory exhausted
but
x_as.data.frame(matrix(scan("data"),byrow=T,ncol=6))
works fine.
read.table is less typing ,I can include the variable names in the first
line and in Splus executes faster. Is there a fix for read.table on the
way?
