How can one get the number of functions and data sets in a package?
I've written a function "PackageSum2" to get an extended package
summary for an installed package. I get much of what I want from the
object returned by "help(package=pkgName)". For example,
"help(pac=...)$info[]" is a character vector giving author,
maintainer, date built, etc. "help(pac=...)$info[]" is a character
vector with at least one row for each help page; I can get the number
of help pages by subtracting the number starting with blank (" ") from
the length. And "help(pac=...)$info[]" is a character matrix
describing the vignettes.
Is there a reasonably easy way to get numbers of (a) functions and
(b) data sets in the package?
I want this for a the next version of "PackageSum2" in the
"RSiteSearch" package. Based partly on previous input from this list,
the package is being renamed to "sos" with the primary
"RSiteSearch.function" function being renamed to "findFn". You can
install the current development version via 'install.packages("sos",
