[R] What does it mean by skip=2 and skip=7?

[Tung86]

Can anyone tell me what is skip=2, skip =7 and %in% mean here?


fromcsv=read.csv
('2_2005_top200_postdoc.csv',header=FALSE,skip=7,stringsAsFactors=FALSE)


fromreadxls = read.xls
('2_2005_top200_postdoc.xls',stringsAsFactors=FALSE,header=FALSE,skip=2)


fromreadxls = fromreadxls[fromreadxls$V7 %in% c('Public','Private'),]



Thanks!
