In R: how to access the index in library(help = "pcks_name")?

I would like to 开发者_运维知识库access the list of functions and their descriptions that is given in

library(help = "pcks_name")

My ideal would be to have this list exported into a file (txt, html, pdf).

Thanks.

You could do

res <- library(help="MASS")
class(res) <- "list"

and access res$info[[2]]
