R help - Feb 2009 - 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.

I think you are looking for the list obiect (the data.frame is a 
particular list with the constrain that each element have to be of the 
same length).
