[R] read.table() and scientific notation

Dear all,

I am having troubles importing values written as scientific notation using read.table(). I'm sure this is a frequent problem, as many people in my lab have this problem as well, so I'm sure that I just have troubles googling for the right solution.

The problem is, that, given a file like that:

a 1 2e-4
b 2 3e-8

the third column gets imported as a factor, or a string if I set the as.is parameter of read.table to TRUE for this column. However, I just want a simple numeric vector :-) I'm sure there is a simple trick for this. If you can point me to the right function, or manual, I think I should be able to find out the details myself.

Thanks in advance,
