[R] gsub/strsplit with multiple patterns/splits

[mdvaan]

Thanks! That works like a charm, but I am not sure if I fully understand the
syntax. I looked at the gsub page but still couldn't figure it out. What
does the pattern part (",{0,1} Inc[.]{0,1}") do? What do the 0 and 1 within
the curly brackets refer to? Also, what if, for example, I would want to
remove the word "Energy"?

Thank you very much in advance.
