Hi Paul,
The easy to understand way is:
n <- c(1:10)
# Create empty list to store vectors
list_of_vecs <- list()
# Create n vectors of random numbers - length 10. This works ok.
for (i in n){
list_of_vecs[[i]]<-rnorm(10,0,1)
}
If you really want to use "assign":
for (i in n){
vecname<-paste('vec_', i, sep = '')
assign(vecname, rnorm(10,0,1))
list_of_vecs[[i]]<-get(vecname)
}
