Getting help on two functions with the same name in two different packages

问题

I know how to use two functions with the same name in two different packages, like packageName:::functionName. But help(packageName:::functionName) does not work even though ?packageName:::functionName. This is strange to me. Any thoughts.

library(plyr)
library(reshape)

plyr:::rename
reshape:::rename

help(plyr:::rename)
?plyr:::rename

Read help(help). You can use help(rename, plyr) to get the documentation for plyr::rename.
