R help - May 2012 - gsub/strsplit with multiple patterns/splits

Hi,

I have a vector like this:

DF <- c("Aetna, Inc.", "Alexander's Inc.",
"Allegheny Energy, Inc")

For each element in the vector I would like to remove the
"incorporated"
info, so that my vector looks like this:

DF <- c("Aetna", "Alexander's", "Allegheny
Energy")

That means that I have to strip:

strip <- c(", Inc.", " Inc.", ", Inc")

How do I pass multiple patterns/splits to gsub/strsplit?

Thanks!

Math

Try this where you qualify how many characters you might match:
> gsub(",{0,1} Inc[.]{0,1}", "", DF)
[1] "Aetna"            "Alexander's"     
"Allegheny Energy"
