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"

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])


How would I go about appending z to an existing list? 

Thanks a ton...
