dear uwe ligges,
thanks for your response. i have problems when importing and handling large
data sets in R. i know read.table() is not optimal for it. what i want to
know how to deal with large datasets efficiently in R with respect to
1. importing large data from a text file
2. subsequent manipulations in R
and also some general guidelines to improve efficiency.
thanks and regards

b. Read "An Introduction to R" (data manipulations)
(both available at CRAN)
To your questions:
2. What kind of answer do you expect ???
