string vector of explicit function names from pkg
to view.
numeric value: 1 = function names only, 2 = function names with brief description, 3 = functions and their arguments, and 4 = function R-code (default).
allows user to specify two additional arguments for output=2
:
remote
- character string giving a valid URL for the R_HOME
directory on a remote location;
update
- logical: if TRUE
, attempt to update the package
index to reflect the currently available packages.
(Not attempted if remote
is non-NULL
.)
Also, if user specifies pat=TRUE
, then funs
, if specified,
are treated like patterns.
Invisibly returns source code of all functions in the specified package.
The function invokes openFile
to display the results.
If funs
is not specified, then all functions, including
hidden (dot) functions are displayed.
If the package has a namespace, functions there are also displayed.
