find all functions (including private) in a package

Question

I know ls(\"package:grid\") and find.funs(\"package:grid\") in mvbutils but apparently neither of them can find non-exported functions

Answer 1

you can use asNamespace:

> methods(cbind)
[1] cbind.data.frame cbind.grobGrid   cbind.ts*       

   Non-visible functions are asterisked
> r <- unclass(lsf.str(envir = asNamespace("stats"), all = T))
> r[grep("cbind.ts", r)]
[1] ".cbind.ts" "cbind.ts" 

cbind.ts in stats package is invisible but can find in envir = asNamespace("stats").
