Mathematica v8: import a space-delimited table of numbers?
Posted:

I routinely use Import[] for "CSV" and "TSV" files, but now need to
import a space-delimited file in which each line has a string as the
first element, and then thousands of (space-delimited) decimal numbers.
After looking at the help documentation, and previous posts on
MathGroup, I don't see a simple way to Import while specifying that the
separator is a space (in R's read.table, I'd use sep=" ").
I expect that I could read in the file as a table, split lines on
spaces, then map ToExpression across the numbers in each row. Have I'd
missed something in the documentation?
Thanks for your help.
