[Rd] help.search() in html?
Hi, I have options(help_type=html) in my .Rprofile and when I type ?foo, the man page appears as a new tab in my web browser (which is already running). Fine. However, when I type ??foo, rather than the results appearing in a new tab, a new instance of the web browser is spawned with the default homepage displayed. Same with help.search(foo). Am I the only one seeing this? Is there some setting/option that I am missing? (At the moment, I bring up a man page via ?foo and then manually follow the Index link at the bottom of the page to go up to the search engine page.)

Re: [Rd] requesting a new SIG mailing list
All, Is it decided then? It does make sense to me, because much of the hydrologic work that we do is related to aquatic ecology. I am responsible for coordinating the migration to use R as the supported statistical package within the Water Mission Area of the USGS. I'd expect that many of our hydrologists will be interested in subscribing to r-sig-ecology to keep up with fellow researchers. I am also sure that some will be frustrated because they will need to wade through material not directly related to their work. When I hear r-sig-ecology will be the forum for hydrology, I'll notify the transition team so that they can subscribe and other hydrologist as they start to use R. Thanks.

I read section 1.5.2 of the manual which mentions three options two of which involve negotiating with CRAN administrators.

It would seem that I need to ensure that my package works under both architectures (32 and 64 bit). 1) Would this be sufficient to get it accepted? 2) If so, does anyone have any documentation in performing this task, or can someone point me in the right direction?

I think you should ask the CRAN administrators that, but my understanding is that they are unlikely to accept your package as described. CRAN is interested in platform-neutral packages, and if you have an .exe, you're going to be Windows-only. If you include the source code for that .exe and put together the Makefile to compile it, then they'd be more receptive, and someone might offer help to get it to run on other platforms if it doesn't on your first attempt.

I think that r-sig-env would be much more intuitive for environmental scientists coming from fields different from ecology, but I don't think it is possible to change the name of an existing mailing list. However, I'm wondering if it would be possible to create an alias termed 'r-sig-env' to 'r-sig-ecology' ?, in order to make the name of the list more intuitive for environmental scientists but without disturbing the current users. I don't know that there is any mechanism for doing either of those things. Changing the name would be disruptive, and I don't know of an alias option. I think ecology is a more inclusive term than environmental anyway, but then I'm an ecologist.

Re: [Rd] R CMD SHLIB in Windows XP - No output at all
Does the following example help? I installed Duncan Murdoch's

I put a small file of C code into E:\temp\junk.c. Here is record
of what I did after opening a new cmd.exe window. Setting PATH

You might want R_HOME\bin early too, if you already have some other R_HOME
