[R] select levels of factor variables

[zoe.cryocla]

Hi again,
I've got another question...


I often use the symbol == to select some levels of factor variables like :
data[data$var=="blabla", [

But this time, I'd like to select all the levels of my variable wich contain
the letter "B", is that a way to determine this conditions ?

Thanks a lot !

Zoé
