showHelp {PBSmodelling} | R Documentation |
Display the help pages for installed packages that match the supplied pattern in an HTML browser window.
showHelp(pat="methods")
pat |
string pattern to match to package names |
The specified pattern is matched to R-packages installed on
the user's system. The code uses the PBSmodelling
function openFile
to display the HTML Help Pages using
a program that the system associates with html
extensions. On systems that do not support file extension
associations, the function setPBSext
can temporarily
set a command to associate with an extension.
A list is invisibly returned, comprising:
Apacks |
all packages installed on user's system |
Spacks |
selected packages based on specified pattern |
URLs |
path and file name of HTML Help Page |
Help pages are displayed in a separate browser window.
The connection time for browsers (at least in Windows OS)
is slow. If the HTML browser program is not already running,
multiple matching pages will most likely not be displayed. However,
subsequent calls to showHelp
should show all matches.
