ESS has a feature to track the occurrence of library(...) if you invoke
it from the prompt, and resets cached objects. If you send
"library(...)"  from another buffer ESS doesn't detect it.

ess-library didn't reset it either,  not it does.

The above unreliable detection will probably go away in the close
future,  but not for the next ESS release. For time being you can use
the universal argument to force updating of the help topics.
