Try:

help(pack="reshape")

Do you see  a listing for rbind.fill? I don't.

If you cannot find a function then try:

??rbind.fill

Maybe they loaded a different package? Or perhaps one that attached the package that has rbind.fill?

My suggestion ( which is only slightly disingenuous, since I do know what package has the forenamed function), is to "learn to fish":

# Either:

install.packages("sos")
library(sos)
findFn("rbind.fill")

# Or:
Google it.
