I'm simulating some experiment by "for" function.
The problem is that it takes too much time.
for example,
a<-list()

I heard there is solution but i don't have idea.
Can anyone help me?

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?
