extracting components of output

[JedSimons@aol.com]

I remember reading about a function which extracts just one component of the output of another function.

eg if the output was from fitting a model, each word (or so) of the output could be accessed an subscript index.

I cannot remember the name of the function, or find it anywhere.  Does anyone happen to know ?  (I'm using Splus 6 under windows.)
