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.

You shouldn't. There is no reason to do this.

No! -- Thank goodness! R is a programming language to begin with. Have you read "An Intro to R?' If not, why not? There are numerous resources available on CRAN to help you. Use them.
Please help me.
Please first make an effort to help yourself. -- Bert
