Thanks for all the replies!
I think I posted a poor example, but now I understand that you can name entries
in a list. That is really neat.
Before I was just letting them default, which is kind of problematic.
I think I also came across another way and also used the suggestion from Bert
Gunter - thanks again:

?c
but you have to make sure z is a list:
c(pts,z) ## probably is not what you want
c(pts,list(z)) ## probably is, but z will be unnamed
c(pts,list(z=z) ## names z "z"

Subject: [R] Appending Data to A n Existing List...
What steps can be take to append data to a list?
Suppose I have the following list and want to append a z axist to the list?
pts <- list(x=cars[,1], y=cars[,2])
z<-rnorm(max(dim(cars)))
How would I go about appending z to an existing list?
Thanks a ton...
