Your email has become a bit distorted during transmission. If you
have used the summary command you should be getting some more summary
statistics. The lm function in R returns an object of class "lm"
which is a list containing at least the components listed in the help
files for lm. The objects in the list are used to produce the summary
statistics.
If you are doing more elaborate work this approach (like the use of
internal functions in gretl) is very convenient.
