Generate object names from variables
I collected some advice about this question a couple of years ago. This might help. http://pj.freefaculty.org/R/Rtips.html#2.1 "Add variables to a data frame (or list)" and the next one after that.

Hi, I want to generate object names out of variables in a sort of variable substitution. first i generate some vectors and an empty list:
vector.a<-c("a","b")
vector.b<-c("c","d")
vector.c<-c("e","f")
vectors<-c("vector.a", "vector.b", "vector.c")
vectors
[1] "vector.a" "vector.b" "vector.c"
vectorlist<-list()
What I would then like to do is to generate elements of the list by using variables, somehow like this (does not work):
for (i in vectors) {
+ list$i<-i + } To end up with a list like this:
list
$vector.a [1] "a" "b" $vector.b [1] "c" "d" $vector.c [1] "e" "f" Any hint will be appreciated. Cheers, Georg
