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?
