R help - Sep 2014 - Obtain 00Index.html

Hello,

how can I open (by an R command) the index page in html mode, as obtained by:

options(browser="firefox") # or any other
options(help_type="html")
?help
# and then following the html reference on the page bottom named
"Index"

In text mode I know library(help='utils') to open the utils package
index (as in the example above). Setting options(text_mode="html") and
options(browser="firefox") does not affect this behaviour. Also in
?help.start and ?help (or ?"?") I found no clues.

Thank you for any hints,
Sven.

There is no built-in function that opens that page.  If you want to
write one, the URL is

http://127.0.0.1:XXXXXX/library/PPPPPP/html/00Index.html

where

  -- XXXXXX is the port being used for the help system, available via
tools:::httpdPort.  (If that is 0, call tools::startDynamicHelp() to
start it up.)

  -- PPPPPP is the name of the package whose index you want.

You can look through the tools:::httpd function for other patterns.
