[R] How to import data from a text file in R

[dilo88]

Hi,

I'd like to import a 154x1 vector of a stock monthly returns from a text (or
excel spreadsheet) into R. I need to work on this vector by calculating
mean, variance and use it for more complex operations. What is the best
function to do so? There are no headers, just 154 decimale numbers (so there
also negative numbers).

Thanks,

Claudio
