Better yet, remove the which altogether, and it'll run a slight bit faster
and maybe look a little neater.
x <- x[x!="bobo"]

No. That does the opposite of what you describe.
You do
x <- x[-which(x=="bobo")]
or better
x <- x[which(x!="bo
Example :
*x=c("abba","bobo","cocoa")*
In order to remove "bobo" from *x* you need to do the following:
*x=x[which(x=="bobo")]*
In case you already know the index of the element you want to get rid of, it
is even easier
*x=x[-elem.index]*
Good luck
