Hello All:
What do you think of adding a function "RSiteSeach" to the package
of that name, masking the "RSiteSearch" function in "utils", trapping
any call RSiteSearch('searchstring', 'function') to the current
RSiteSearch.function and passing all others to "utils:::RSiteSearch"?
This was suggested by a referee to a manuscript on this new capability
submitted to "R Journal". The current version of this manuscript is
available via "system.file('doc', 'RSiteSearch.pdf',
package='RSiteSearch')" if you have the "RSiteSearch" package installed.
Thanks,
Best Wishes,
Spencer

I agree! Recall, though, I had added the RSiteSearch() functionality
to the Rgui under Windows (Help / search.r-project.org...), so if
RSiteSearch() is taken out, this need to go, too.

There is something to be said for taking all of these functions,
including the original RSiteSearch, out of utils and putting them in
the new RSiteSearch package. These are the sorts of things that will
get revised frequently, and this way (I think) we won't have to bother
whoever takes care of utils, which is part of the regular R
distribution.
I'm adding Spencer Graves to the cc list. Maybe he is interested in
doing this.

We could have a few functions similar to RSiteSearch or
gmaneSearch I
just posted and then cook a summary html page with R ...
Here is a function that grabs relevant groups from gmane:
gmaneGroups <- function( prefix = "gmane.comp.lang.r." ){
url <- URLencode( sprintf(
"http://dir.gmane.org/index.php?prefix=%s";, prefix) )
txt <- grep( '^<tr.*<td align=right.*<a', readLines(
url ), value =
TRUE )
rx <- '^.*?<a href="(.*?)">(.*?)</a>.*<td>(.*?)</td>.*$'
out <- data.frame(
url = gsub( rx, "\\1", txt ),
group = gsub( rx, "\\2", txt ),
description = gsub( rx, "\\3", txt ),
stringsAsFactors = FALSE
)
out$group <- sub( "...", ".*", out$group, fixed = TRUE )
out
}
I'll clean this up and write a man page if there is
interest in adding
this to R, but this might be more appropriate in a package,
for example:
http://r-forge.r-project.org/projects/rsitesearch/

I'll incorporate the changes if you like
Yes. Please do. I understand that it won't take effect
for a while.
When it does, I'll change my site.
What do you think
of the idea
of adding a gmane (or other archive) search to your results
page? Then
if someone doesn't like what the man pages show, you can
send them
somewhere else, rather than leaving them to find out the
other resources
themselves.
gmane has sample code for this on their search page
search.gmane.org, so
it looks reasonably easy. I'd suggest following their
last example,
with a drop-down box to select mailing lists, with
comp.lang.r.* as an
option for "all lists".

Good idea. I will do this. But there are also two
other good search
engines. Maybe I'll add all three search alternatives.
But then,
according to Sheena Iyengar, people won't choose any! Hmm.
Actually, I was thinking about a possible RHelpSearch() in
addition, if
Jon is no longer going to include the R-help archive in the
search. I
used the current RSiteSearch() a lot more for searching
R-help archive
than functions in packages. Ideas? comments?
This is OK with me, but I don't want to do it. I guess it would
search gmane. MarkMail is also pretty good, as is
http://tolstoy.newcastle.edu.au/R/ All these are much better than
Namazu for searching the R-help list.
Sorry I didn't make it clear: I meant something like the
gmaneSearcg()
that Romain posted, not hitting your site.
Best,
Andy
