So I have a list variable, and each item has a name. Is it possible to
return just the names in the list and not the contents of each one?
?names
Example:
Currently, if I have a list variable "matrices", and it contains 3
matrices, "M1", "M2", and "M3", if I type:
matrices, R returns $M1 -> listing of numbers in matrix; $M2 ->
listing of numbers in matrix, and $M3 -> listing of numbers in the
matrix.
Is there a way to have it return only the names $M1, $M2, $M3?
I know this seems trivial and I'm sure it has been asked before, but I
can't find it.
Thanks in advance.
