How about this one? If I set a variable in a data.frame with a two- part name including a dot (say y.pair), and if the variable with the name of the first part (y) doesn't but I ask for it's value I get the value of the two-part name. Ie set fred$x.pair and print the value of fred$x it gives me the value I set to fred$x.pair. Weird and somewhat disturbing! Maybe an example makes it

There must be a simple answer. I want to plot an expression, where the expression is held in a string variable. The "obvious" solution along the lines of ex<-"x^2" plot( c(0,1), c(0,1), main=as.expression(ex) ) gives me the a title x^2 - ie doesn't treat it like an expression. I suspect I don't understand expressions properly. For the real problem I do need to

Anybody out there successfully using the Salford Fortran compilers with R? I have created a DLL using the Salford FTN95 compiler and it works in as far I can dyn.load it, run the routines and get the right answers back. Unfortunately subsequently, sometime later, the Rgui crashes (access violation I think from the DrWatson log). The crashes depend on whether or not I paste the code as one

Dear R People: Sorry for the off-topic. Could someone recommend a good reference for using the EM algorithm on mixed models, please? I've been looking and there are so many of them. Perhaps someone here can narrow things down a bit. Thanks in advance, Sincerely, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown

Dear all, One for the windows graphics developers I guess.... I seem to have hit a bug in the line drawing in windows (default device or explicit calls to win.metafile). As the line segments used to plot a curve get smaller (increased resolution) the line drawn seems to get less smooth rather than more smooth, and starts to break up.. Attached is a toy example drawing a quadratic with

Greetings. One for the developers I guess... I am having problems in using a (non-recommended) Fortran compiler (Salford ftn95 Windoze), and the crashes do seem to be associated with the ftn95-dervived DLL changing the Floating Point Control Word. The compiler people are suggesting (and I paraphrase!) that if R minds what the FPCW is it is up to R to make sure it is the value it wants and

Greetings. There seems to be a problem with the P-value computation in the cor.test with method="spearman". In R1.8.0 (MS Windows) I seem to be getting intermittently nonsense P-values, but the rho's are OK. I can get this reproducibly with the toy example attached where the first use is OK and subsequent calls with the same data give nonsense. (I have also seen the problem

Let me modify my question about user-defined covariance structures for LME models: Can somebody tell me how I can see the code for the definition of the correlation structures that come with the NLME package. Specifically I like to see the code for the functions coef, corMatrix, and intialize for any of the pre-defined correlation structures, and use this as a template to define a new correlation

L.S. Since some time there is a new r-project.org site as announced here: https://stat.ethz.ch/pipermail/r-announce/2015/000581.html The logo has changed on the site, but I fail to find a vector graphics file. For the previous logo I used to go to https://svn.r-project.org/R-dev-web/trunk/Logo/ Is there anything similar for the new logo? Many thanks in advance. Kind regards, Tobias --

Full_Name: Tobias Verbeke Version: 2.1.0 OS: GNU/Linux Submission from: (NULL) (81.247.252.229) Would it be possible to use a non-ambiguous example of expressing a day according to the ISO 8601 international standard in the first sentence of the Note section of ?strptime, e.g. "2001-04-18" instead of "2001-02-03" ?

Hallo, does a package for Matlab exist in R? If yes, where can I find it and how can I install it under R? Thanks, Corinna

Hi, Is it possible to configure NTLM HTTP proxy authentication using the winbind/squid "ntlm_auth" helper, to authenticate users against a Samba 3 server? I already have the NTLM auth working against a Windows 2003 Active Directory, but I also have a completely separate Samba 3 server that I would also like to configure NTLM proxy authentication against. Please advise, as I can't

L.S. In this bug report https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14493#c1 it is mentioned that after moving an R installation one should regenerate the Rscript executable. Is there an easy way to do so (after an R installation has been moved)? I have not found any information in the R installation and administration manual. Many thanks in advance for any pointer. Best wishes,

Many thanks, Duncan. We will check the prerelease versions of R 3.2.1.

I am using Mandrake 8.0 (on /dev/hda5) with Windows 2000 (on /dev/hda2) mounted as /mnt/win2000 and the windows swap file (on /dev/hdb12) mounted as /mnt/k. I installed wine-20010305-1.i386.rpm and then ran winesetup. When it got to Autodetect I got following message: Unable to detect any users on WinNT/2k partition mounted on /mnt/k. This means that this windows installation is probably

Hi, I have been using R for a while. Recently, I have begun converting my package into S4 classes. I was previously using Rdoc for documentation. Now, I am looking to use the best tool for S4 documentation. It seems that the best choices for me are Roxygen and Sweave (I am fine with tex). Are there any users of Roxygen or Sweave who can comment on the strengths or weaknesses of one or othe

L.S. I noticed the NEWS file as made available at http://cran.r-project.org/src/base/NEWS became inconsistent in describing CHANGES for a new R version: $ wget http://cran.r-project.org/src/base/NEWS $ cat NEWS | grep 'CHANGES IN ' CHANGES IN 3.2.0: CHANGES IN R 3.1.3: CHANGES IN R 3.1.2: CHANGES IN R 3.1.1: CHANGES IN R 3.1.0: CHANGES IN R 3.0.3: CHANGES IN R 3.0.2: CHANGES IN R 3.0.1:

Dear list, Is there an exact formula / safe rule of thumb that allows one to express the value of --max-ppsize as a function of the value of getOption("expressions") ? ?options tells "If you increase it [the expressions option], you may also want to start R with a larger protection stack". Motivation is to determine stack size of a Java vm used to launch R with a given

Dear R help list members, I am experiencing difficulty in trying to generate a subscript '2' in an axis label. Although I can get the '2' into a subscript using expression(), R then forces me to leave at least one space between the '2' and the following character. My label is supposed to read 'N2O concentration (ppm)', and the space between the '2' and
