Hi all,
I have a problem with retreaving column from a data.frame that is
I have a data.frame named "temp"
in that dataframe some column are there whose names are
"IDENTIFIER""UNIQUEID" "TRIALGROUPSID" "GRPNUMBER"
"GRPDESC" "SEXDID""STDID" "STUDYTYPE"
"SDID"
Maybe you want something like this.
temp<-data.frame(id=rbinom(10,5,.5),grp=rbinom(10,3,.3),stdid=rnorm(10))
kk<-"stdid"
temp[,kk]
-tgs
