help.start(update = FALSE, gui = "irrelevant",

remote
is non-NULL
.)remote
is specified this requires the HTTP server to be
available (it will be started if possible: see
startDynamicHelp
). One of the links on the index page is the HTML package index,
make.packages.html()
. For local operation,
the HTTP server will remake a temporary version of this list when the
link is first clicked, and each time thereafter check if updating is
needed (if .libPaths
has changed or any of the
directories has been changed). This can be slow, and using
update = TRUE
will ensure that the packages list is updated
before launching the index page.
Argument remote
can be used to point to HTML help published by
another Rinstallation: it will typically only show packages from the
main library of that installation.
help()
for on- and off-line help in other formats. browseURL
for how the help file is displayed.
RSiteSearch
to access an on-line search of Rresources.
help.start()
#ifdef unix
## the 'remote' arg can be tested by
help.start(remote = paste0("file://", R.home()))
