proposed changes to RSiteSearch
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:

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
