If a vector has elements of different types, it is called a list in R programming. Lists are copied element-by-element into a pairlist and the names of the list used as tags for the pairlist: the return value for other types of argument is. > sapply( names(sapply(mylist, names)), function(x) mylist]^2) Sort the items of the list in place (the arguments can be used for sort customization, see sorted() for their explanation). > #get name of list elements ("a", "b", "c") > through the list elements themselves and access the element names
