R help - Jun 2007 - add line to data.frame

Dear R user,

how can I update a data.frame adding new lines?
I need to create a second data frame from a first one with only some of their 
entrys filtering the value of a specific column... How can I do this?

thankyou very much in advance
best regards
	Manuele PEsenti
