R help - Feb 2012 - replace elements of a data frame

Hello,

I am getting mad at finding a simple way to replace elements of a df.

Here is a short df :
> names<-c("BO","C","CL")
> price<-c("10","25","20")
> df<-data.frame(names,price)

I want to replace "BO" by "BOB", "C" by
"CR", "CL" by "CLO", and the list is more long.
I can do that for each element:
>df[df=="BO"]<-"BOB"
But my df is bigger indeed with other elements.

I was thinking using replace(), but can't get any clean result ( NA or all
elements replaced with only one), neither with sapply().

TY for any help, and sorry for the n00b question.
