Answer 1

List elements in R can be named. So in your case just do

 > mylist = list()
 > mylist$width = value

When R encounters this code

> l$somename=something

where l is a list. It appends to a list an element something, and names it with name somename. It is then can be accessed by using

> l[["somename"]]

or

> l$somename

The name can be changed with command names:

> names(l)[names(l)=="somename"] <- "othername"

Or if you now the position of the element in the list by:

> names(l)[1] <- "someothername"
