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.

I really appreciate to your attention. I want to change the data form "A" into "B" http://r.789695.n4.nabble.com/file/n4428807/1.png http://r.789695.n4.nabble.com/file/n4428807/2.png In fact, there are 1095 column in data "A". Specifically, variable "publish_day" is when some book in the same row is published and "D-1", "D-2" means the term after the "publish day". Of course, the cells in data mean productivity in the day. What can be effecient way to do it? -- View this message in context: http://r.789695.n4.nabble.com/macro-function-tp4427385p4428807.html Sent from the R help mailing list archive at Nabble.com.

Asking how to create 1000 separate variable is almost certainly to be the wrong way to go. If you wanted a list with names like that we can probably help. -- David Winsemius, MD Heritage Laboratories West Hartford, CT
