I noticed the same thing as I reported below, when I upgraded from R-2.0.0-alpha-20040918 to today's beta version: 'R CMD check' failed as before; but after cleaning 'src' from .o and .so files, it worked again. So the two-day-old '.so' file is obviously different from today's. Has compiler directives changed in the two last days? Or what is happening? G?ran On

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

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 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 <-

Now I try to add some C and Fortan code to my package, so the NAMESPACE file is useDynLib(eha) importFrom(survival, Surv) export(mlreg.fit, risksets) but I get ..... * checking R files for library.dynam ...

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

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

This is a question that I should have sent to 'ess-help', but I take my chances... In 'NEWS' (1.9.0) I read the good news o Underscore '_' is now allowed in syntactically valid names, and make.names() no longer changes underscores. Very old code ... but when I try it in emacs (ESS 5.1.24), my '_' are changed to ' <- '! What can I do?

A few days ago I uploaded to CRAN a new package called 'eha', which stands for 'Event History Analysis'. Its main focus is on proportional hazards modeling in survival analysis, and in that respect eha can be regarded as a complement and an extension to the 'survival' package. In fact eha requires survival. Eha contains three functions for proportional hazards

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 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

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

I need to order a long vector of integers with rather few unique values. This is very slow: > x <- sample(rep(c(1:10), 50000)) > system.time(ord <- order(x)) [1] 189.18 0.09 190.48 0.00 0.00 But with no ties > y <- sample(500000) > system.time(ord1 <- order(y)) [1] 1.18 0.00 1.18 0.00 0.00 it is very fast! This gave me the following idea: Since I don't care

I'm trying to learn how to use namespaces, so I have created a small package with two functions. My NAMESPACE file is importFrom(survival, Surv) export(mlreg.fit, risksets) because 'mlreg.fit' uses 'Surv' from 'survival'. However I get * checking package dependencies ...

I find 'How do I convert factors to numeric?' in the FAQ (7.12), but not the other way around. Trivial maybe, but > codes(factor(c(2, 10)) [1] 2 1 > codes(factor(c(2, 9))) [1] 1 2 How do I get the levels attached to the codes in numeric order?
