As far as I discovered from a quick google query the Excel
command you cite selects some values from a table according 
to some conditions.
So if you have a data frame called example you could do 
something like 
example[example$var1>5,] 
Perhaps you need something like
example[example$var1>5,2:5]
or 
example[example$var1>5,]$var2.

Anyway you should follow the advice you'll find at the end of 
the message:

... or at least a good example of what you would like to obtain!

You'll find a lot of informations on the manipulation of data frames
in the manuals.
go to http://www.r-project.org/, select "manuals", go to the 
"Contributed Documentation". You'll find various manuals,
also ones in italian.
