Is it possible to let a function be known under two names without having two identical copies of the function body? --- G?ran Brostr?m tel: +46 90 786 5223 Department of Statistics fax: +46 90 786 6614 Ume? University http://www.stat.umu.se/egna/gb/ SE-90187 Ume?, Sweden e-mail: gb at stat.umu.se

I have a data frame containing children, with variables 'year' = birth year, and 'm.id' = mother's id number. Let's assume that all the births of each mother is represented in the data frame. Now I want to create a subset of this data frame containing all children, whose mother's first birth was in the year 1816 or later. This seems to work: mid <-

When reading an spss file, I get the following message: Warning message: ../totmorH.sav: Unrecognized record type 7, subtype 13 encountered in system file. What does it mean? Do I have to worry? The result looks as expected. I do not have (easy) access to SPSS, so I cannot check exactly that I got what I should have. Thanks, G??ran And, I'm using R-2.0.1 on Debian testing (from source).

I will be giving a course in survival analysis using R (of course!) for people who know nothing about the subject (including R), but know basic statistics. I'm looking for a suitable course book. Therneau & Grambsch (2000) is an excellent book, but too much for this course. I need somthing more elementary. I have a vague memory saying that such books exist, but I cannot find any for the

I'm looking for a Windows distribution of TeX that works with R, after a few years' absence from Windows. On Duncan Murdoch's Rtools page fptex is still recommended, but it turns out that fptex is "defunct" as of May 2005, see http://www.metz.supelec.fr/~popineau/xemtex-7.html So, what is suggested? TUG (tug.org) recommends something called proTeXt, which is said to be

Hi I know some of this has been discussed in the past but I can''t quite find the exact information I''m seeking (and I''d check the ZFS wikis but the websites are down at the moment). Firstly, which is correct, free space shown by "zfs list" or by "zpool iostat" ? zfs list: used 50.3 TB, free 13.7 TB, total = 64 TB, free = 21.4% zpool iostat: used

Hi, I am able to reproduce the following panic on a number of Solaris 10 06/06 boxes (Sun Blade 150, V210 and T2000).

Dear R-helpers, In a data set I got from a medical doctor there are six treatment groups and (about) 5 bivariate responses in each group. Using 'manova', it is easy to see significant differences in treatment effects, but the doctor is more interested in the correlation between the two responses (within groups). I'm willing to assume a common value over groups, and one way of

I have two versions of R on my Debian testing: R-1.9.0 (precompiled) and R-1.9.1-alpha of 2004-06-07 (built on my system). In the latter, I get > system("emacs sim.R &") > emacs: standard input is not a tty while with R-1.9.0 it works as expected. I have absolutely no idea about what's going on, so I could use some help. Anyone? Thanks, G?ran -- G?ran Brostr?m

I have been bitten by what is clearly described on the help page for 'sample', namely sampling from a population of size one. I agree that it is convenient to have an exception if 'length(x) == 1', but my suggestion is to enforce the exception only if 'x' is numeric. In any case, if x is not numeric and of length 1, all you get is an error message. I would like

I am calling 'vmmin' several times from a C function (which is called via .C). It works very well, except for memory consumption. The cause is that vmmin allocates memory via R_alloc, and this memory is not freed as vmmin exits. Instead all the allocated memory is freed on return of the .C call. In one application, I have 2000 functions of 500 variables each to minimize. In each call to

Reading about 'R_max_col' in "Writing R extensions", Version 2.1.0,(2005-01-03), I find: "Given the nr by nc matrix matrix in row ("FORTRAN") order, ..." Looks like a contradiction to me, since FORTRAN stores matrices columnwise. So is this a documentation bug? -- G?ran Brostr?m tel: +46 90 786 5223 Department of Statistics

I have both gcc-3.4 and gcc-4.0(.1) installed on my system (debian-amd64 unstable), with links /usr/bin/gcc, g77, etc. to the 3.4 versions. When I build R, the 3.4 version is picked up, which is fine. However, when I 'install.packages("xyz")', R uses gcc-4.0 and gfortran-4.0! Should I accept this or do something about it? And if so, what? Of course, removing all 4.0 versions

For some reason I want to let one data set in a package be known under two different names. Is that possible, and if so, how? I do not want to have two copies of the data set in the package. Thanks, G?ran -- G?ran Brostr?m Department of Statistics Ume? University SE-90187 Ume?, Sweden

I use Gnu emacs 21, Linux RH9 and R-1.7.0. I have succeeded to get the recommended indentation of 4 in C thru customization as described in 'R-exts', p.73, but I can't get it to work in R code. Can someone help, for instance by sending me the appropriate lines in '.emacs'? Thanks! --- G?ran Brostr?m tel: +46 90 786 5223 Department of Statistics
