How to google for R stuff?

See http://finzi.psych.upenn.edu/
for many options for searching for R stuff.

If you type R into Google, the R home page usually comes up first.  I
was amazed when this happened 9 years ago.

And now, if I type "R lmer" into Google (without the quotes), a whole
bunch of relevant stuff comes up, although it isn't so systematically
arranged as with the other search options.

www.rseek.org is the best solution to this that I have found.

There are loads of ways of finding information.

Use the function RSiteSearch, or
The R mail archive              
http://www.googlesyndicatedsearch.com/u/newcastlemaths
RSeek                           http://www.rseek.org/
R Search                        http://www.dangoldstein.com/search_r.html  

The R Graph Gallery             http://addictedtor.free.fr/graphiques/
R Help Wiki                     http://wiki.r-project.org/rwiki/doku.php
R manuals                       http://cran.r-project.org/manuals.html

R-Forge (http://r-forge.r-project.org/) and Bioconductor (
http://www.bioconductor.org/GettingStarted) also have their own search 
tools.

Hi Kynn,

I've had this problem too in the beginning. Luckily, my personal 
experience has taught me that almost all relevant R-related information 
can be found either by searching directly through the archives of the 
different R-forums or by using the functions "RSiteSearch()" or 
"help.search()". The reference manuals provided with each package 
(easily accessible on CRAN) are also invaluable sources of information.

Unfortunately, phrasing queries in a way that will yield relevant 
results is sometimes hard. Knowledge of the terminology mostly comes 
from experience, so patience is in order.

Of course, as a last recourse, there's always the mailing list.

Bottom line is, I suggest you try to avoid generic search engines and 
concentrate your efforts on the different R-forums (note that there are 
also package-specific forums).

I suspect the more experienced R-users might have better strategies to 
propose though...

Cheers,

For Google searches, I find that throwing in the term cran on every search helps weed out irrelevant pages.

For example, instead of 

r residuals

I type

r cran residuals

There is also the relatively new "RSiteSearch" package.  It's 
"RSiteSearch.function" searches only help pages of contributed packages 
but returns the result in a data.frame (of class "RSiteSearch") sorted 
to put the most interesting package first with help pages sorted within 
packages.  If this package is installed, "system.file('doc', 
'RSiteSearch.pdf', package='RSiteSearch')" will give you the location of 
a 2-page description of the most important features of this package 
including examples that work.  Since that document was written, we've 
added "|" and "&" for combining the objects returned by different 
searches and "packageSum2" to add information from installed packages 
not available from "RSiteSearch" itself. 


      For example, I'm giving an invited presentation on "Fitting 
Nonlinear Differential Equations to Data in R" as part of a "Dynamics 
Workshop" in Vancouver this June 4-6 
(http://stat.sfu.ca/~dac5/workshop09/Welcome.html).  To prepare for 
that, I first did the following: 


de <- RSiteSearch.function("differential equation")
des <- RSiteSearch.function("differential equations")
# With "de" and "des", each finds things missed by the other. 
de. <- de | des # combine into one
sumDE <- packageSum2(de.) # add details on installed packages. 


      This helped me decide which packages I should look at first. 

      Hope this helps.

I was having the same frustration so I made a Google custom search
engine for Open Math Tools:
http://www.google.com/coop/cse?cx=015659631714008342946:wolsniqtrxc

It gives preferences to results from r-project.org, octave.org,
maxima.sourceforge.net, and the mailing list archives from those
projects.  It also has some other smaller pages that contain tutorials
for those tools.

It includes results from the broader web as well, so if there is a
highly ranked article from wikipedia or mathworld that will show up
too.

Here's a short write-up with example searches:
http://j-stults.blogspot.com/2009/05/open-math-tools-custom-search-engine.html

If any folks on the list out there have any suggestions or would like
to be a 'contributor' on it post a reply with a site to add to the
preference list , or click the 'volunteer to contribute' link on the
search engine homepage.

Good luck with your R searching.

Dear Dieter: 

      Thanks for the correction.  I failed to test the code as written 
before I posted it.

ISTR having this question or very close ones at least thrice in the last
two months.

Time for a FAQ entry ? (It does not seem to exist : I checked...)

You are very picky.  When I enter

R residuals

into Google, 8 out of the first 10 hits are for R topics.  Isn't that 
good enough for you?

I think this is true of most Google searches:  the letter R most often 
means the R project.

A couple more ideas...

If you find reading code useful, try specifying filetype:r in Google
(e.g., do.call filetype:r)

For firefox users, the R wiki provides search tips here:

http://wiki.r-project.org/rwiki/doku.php?id=tips:misc:firefox-search-plugins

My preference is to keep RSeek in the top position of the firefox
search bar so that on my windows box I can Ctrl-Tab to firefox, then
Ctrl-K to search R sites.

hth,
