Something similar to data.frame, but allows variables with unique lengths?

I have a tightly coupled collection of variables with different lengths and types (some characters and others numerics).? I looked at the documentation for data.frame, but indicates that it expects all variables to have the same length, i.e. number of elements.

I was hoping the "See Also" documentation for?data.frame?would have helped, but it did not have any good leads.

Here is a list of data I would like to store together:
(FileName (character string),
?HighValue (numeric),
?LowValue (numeric),
?Units (character),
?OthersValues?(array of numerics),
?Descriptor?(character string))

By any chance is there a generic object type feature within R to store such data together in one variable?

Thank you for any details and leads you can provide.
