Mailing Lists

   Please read the [31]instructions below and the [32]posting guide before sending
   anything to any mailing list!

   Thanks to Martin Maechler (and ETH Zurich), there are five general mailing lists
   devoted to R.

R-announce

   This list is for major announcements about the development of R and the
   availability of new code. It has a low volume (typically only a few messages a
   month) and everyone mildly interested should consider subscribing, but note that
   R-help gets everything from R-announce as well, so you don't need to subscribe to
   both of them.

   Note that the list is moderated to be used for announcements mainly by the R Core
   Development Team. Use the [33]web interface for information, subscription,
   archives, etc.

R-help

   The `main' R mailing list, for discussion about problems and solutions
   encountered using R, including using R packages in the standard R distribution
   and on CRAN; announcements (not covered by R-announce or R-packages); the
   availability of new functionality for R and documentation of R; and for posting
   nice examples and benchmarks.

   This is quite an active list with many messages per day. An alternative is to
   subscribe and choose daily digests (in plain or MIME format). Use the [34]web
   interface for information, subscription, archives, etc.

   Please read the [35]posting guide before sending a message to the list. In
   particular, if asking for help with a problem, it is important to be clear and
   concrete, and it is almost always advisable to send a [36]minimal reproducible
   example of the problem.

   There are many more specific R email lists (see below under `Special Interest
   Groups'). If a problem is appropriate for one of the more specific lists, you are
   usually more likely to get help by posting to the more specific list. For
   example, a problem specific to R under macOS should normally be posted to the
   R-SIG-Mac list, and a problem concerning R software for mixed-effects models
   should normally be posted to the R-SIG-mixed-models list.

   R-help is not intended for help with homework or basic-statistics questions.

   Bugs in contributed CRAN packages should normally be reported directly to the
   package maintainer (use maintainer("package-name") in R). You may also be able to
   obtain help with a problem from the package maintainer.

   Help with R problems is available from a number of sources beyond the R email
   lists. See under `Help' at the [37]R home page.

R-package-devel

   is to get help about package development in R, i.e., to provide a forum for
   learning about the package development process, a community of R package
   developers who can help each other solve problems, and reduce some of the burden
   on the [38]CRAN maintainers. If you are having problems developing a package or
   passing R CMD check, this is the place to ask!

   There may be some overlap of topics with the R-devel mailing list, as before the
   existence of R-package-devel, many package developers had used R-devel instead.
   Beware that cross-posting to both lists is generally considered as impolite. For
   subscription and more, please read and use the [39]web interface.

R-devel

   This list is intended for questions and discussion about code development in R.
   Questions likely to prompt discussion unintelligible to non-programmers or topics
   that are too technical for R-help's audience should go to R-devel, unless they
   are specifically about problems in R package development where the
   R-package-devel list is appropriate, see also [40]the posting guide section. The
   list is also for proposals of new functionality for R, and pre-testing of new
   versions. It is meant particularly for those who maintain an active position in
   the development of R.

   If you don't want to receive more than a daily message, you can subscribe and
   choose digests (in plain or MIME format). Use the [41]web interface for
   information, subscription, archives, etc.

R-packages

   This list is for announcements as well, usually on the availability of new or
   enhanced contributed packages (on [42]CRAN, typically).

   Note that the list is moderated. However, CRAN package authors (and others,
   similarly qualified) can freely post. As with R-announce, all messages to
   R-packages are automatically forwarded to the main R-help mailing list; we still
   recommend to subscribe to R-packages if you read R-help only in digest form. Use
   the [43]web interface for information, subscription, archives, etc.

Special Interest Groups

   Additionally, there are several specific Special Interest Group (=: SIG) mailing
   lists; however do post to only one list at time (`SIG' or general one),
   cross-posting is considered to be impolite.
     * [44]R-SIG-Mac: R Special Interest Group on Mac ports of R
     * [45]R-SIG-DB: R SIG on Database Interfaces
     * [46]R-SIG-Debian: R Special Interest Group for Debian ports of R
     * [47]R-SIG-dynamic-models: Special Interest Group for Dynamic Simulation
       Models in R
     * [48]R-SIG-ecology: Using R in ecological data analysis
     * [49]R-SIG-Epi: R for epidemiological data analysis
     * [50]R-SIG-Fedora: R Special Interest Group for Fedora and Redhat ports of R
     * [51]R-SIG-Finance: Special Interest Group for `R in Finance'
     * [52]R-SIG-Geo: R Special Interest Group on using Geographical data and
       Mapping
     * [53]R-SIG-gR: R SIG on gRaphical models
     * [54]R-SIG-GUI: R Special Interest Group on GUI Development
     * [55]R-SIG-HPC: R SIG on High-Performance Computing
     * [56]R-SIG-Insurance: Special Interest Group on using R in actuarial science
       and insurance
     * [57]R-SIG-Jobs: R SIG List for Announcements of Jobs where R is used
     * [58]R-SIG-meta-analysis: R SIG for discussing the use of R for conducting
       meta-analyses
     * [59]R-SIG-mixed-models: R SIG on Mixed Effect Models, notably lmer() related
     * [60]R-SIG-networks: R SIG for users and developers of network- or
       graph-related software within R
     * [61]R-SIG-phylo: R SIG on phylogenetic and comparative methods and analyses
     * [62]R-SIG-Robust: R SIG on Robust Statistics
     * [63]R-SIG-teaching: SIG on Teaching Statistics (and more) using R

   To satisfy geographic or regional (or subject) needs, some R users have formed "R
   User Groups" for which there are mailing lists. Information about most of these
   groups and their lists can be found on the [64]Revolution page.

Archives and Search Facilities

     * Browsable HTML versions of the mail archives can be found at the [65]web
       interface.
     * Have a look at CRAN's [66]search page for searchable versions of the mailing
       list archives.

General Instructions

   Note that you should configure your e-mail software in such a way as to send only
   plain text, i.e., no HTML. `html-ified' messages are usually considerably longer
   (in bytes!) and harder to filter for spam or viruses. Many of these
   (e.g. `html-only' ones) are currently spam-filtered or otherwise intercepted
   completely and without notice to the sender. For more details and instructions on
   turning off HTML for your e-mail software, see [67]here or [68]there.

   Furthermore, most binary e-mail attachments are not accepted, i.e., they are
   removed from the posting completely. As an exception, we allow application/pdf,
   application/postscript, and image/png (and x-tar and gzip on R-devel). You can
   use text/plain as well, or simply paste text into your message instead.

   Information about the list can be obtained by sending an email with info as its
   contents to [69]r-help-request@R-project.org. Note that you can subscribe and
   unsubscribe by E-mail (instead of the web interface), but to unsubscribe you
   currently need the mailing list password which you get when subscribing and in a
   monthly reminder.

   To send a message to everyone on the R-help mailing list, send email to
   [70]r-help@R-project.org. Do please create a new email message when posting to
   the list rather than replying to a previous message and simply changing the
   subject line! This allows sensible threading in the mailing list archives (and
   many users e-mail readers). Subscription and posting to the other lists is done
   analogously, with R-help replaced by R-announce and R-devel, respectively. Note
   that the R-announce list is gatewayed into R-help, so you don't need to subscribe
   to both of them.

   It is recommended that you send mail to R-help (or R-devel if appropriate) rather
   than only to the R developers (who are also subscribed to the list, of course).
   This may save them precious time they can use for constantly improving R, and
   will typically also result in much quicker feedback for yourself.

   Of course, in the case of bug reports it would be very helpful to have code which
   reliably reproduces the problem, see the [71]entry in the R FAQ.

   about R itself, please consult the [72]Getting Help section.
