[R] How to read this file into R.

[Phil Spector]

Changbin -
    If you want the entire line, use

> readLines('~/ca_boost_feature.txt',warn=FALSE)[2]
[1] " H.2.C C.1.D C.3.R E.0.N C.2.S C.0.G H.3.G"

    If you want a vector with the contents of the line, use

> scan('~/ca_boost_feature.txt',skip=1,n=7,what='')
Read 7 items
[1] "H.2.C" "C.1.D" "C.3.R" "E.0.N" "C.2.S" "C.0.G" "H.3.G"

Hope this helps.
