hi, I know how to use the "for" loop function like:
for(i in 1:ncol(mat)){ mat[i]<-b[i,2] } but, in this case r1<-b[1,1] r2<-b[2,1] r3<-b[3,1] r4<-b[4,1] * * * r3002<-b[3002,1] r3003<-b[3003,1] - must make vectors how should I make a efficient code for that? Is there anything in R like SAS MACRO function? Please help me. -- View this message in context: http://r.789695.n4.nabble.com/macro-function-tp4425446p4425446.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
