For hardware reasons (disk space, CPU performance) there is currently
no search facility at the R master webserver itself. However, due to the
very active R user community (without which R would not be what it is
today) there are other possibilities to search in R web pages and mail
archives:
An R
site search is provided by Jonathan Baron at the University
of Pennsylvania, United States. This engine lets you search help
files, manuals, and mailing list archives.
Searchable mail
archives
of the three mailing lists are provided by
Robert King at the University of Newcastle, Australia.
Gmane's
R-lists mirrors several of our lists, with web, news, and
RSS interfaces and search facilities.
Rseek is provided
by Sasha Goodman at Stanford university. This engine lets you search
several R-related sites and can easily be added to the toolbar of
popular browsers.
The Nabble R Forum is an innovative search engine
for R messages.
Thanks to all of them!
In addition, you can always use the advanced search feature of the Google search engine:
