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.

Dear community,
I have one file named ca_boost_feature.txt,
Feature selection (Boosting:0.0025,5)!
H.2.C C.1.D C.3.R E.0.N C.2.S C.0.G H.3.G
log file: ep
If I want to use the second line of this file, how to read it into R?
varr<-read.table("/home/cdu/operon/carbonic/ca_boost_feature.txt", sep=" ",
skip=1, header=F, strip.white=TRUE, nrows=1)
Warning message:
In read.table("/home/cdu/operon/carbonic/ca_boost_feature.txt", :
incomplete final line found by readTableHeader on
'/home/cdu/operon/carbonic/ca_boost_feature.txt'
I attached this file with this email.
Thanks!
