I have a data set called GQ1, which has 20 variables one of which is a
factor called Status at thre levels "Expert", "Ecol" and "Stake"

I have managed to evaluate some of the data split by status using commands
like:

summary (Max[Status=="Ecol"])

BUT how do I produce  asummary for Ecol and Expert combined, the only
example I can find suggsts I could use

summary (Max[Status=="Ecol"& Status=="Expert"]) but that doesn't work.

Additionally on the same vein, if I cannot work out how to create a new data
set that would contain all the data for all the variables but only for the
data where Status = Ecol, or where status equalles Ecol and Expert.

I know this is yet again a very simple problem, but I really can't find the
solution in the help or the books I have.

Many thanks,

Graham
