macro function

[mrzung]

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 first make an effort to help yourself.
