[Rd] load, environment[[, and attr<-/attributes<- (PR#8457)

Full_Name: Mark Bravington Version: 2.2.1 OS: Windows XP Submission from: (NULL) (203.132.243.69) # [EMAIL PROTECTED] There is a bug to do with 'load', environment access via '[[', and 'attr<-' or 'attributes<-'. Modifying the attributes of a *copy* of an object can modify the original too

[Rd] checkpointing

I would like to checkpoint some of my calculations in R, specifically those using optim. As far as I can tell, R doesn't have this facility, and there seems to have been little discussion of it. checkpointing is saving enough of the current state so that work can resume where things were left off

Martin, I have some tests running over CRAN now (RUnit has also failed), but have already noticed things like > swiss[, 1] -> x > names(x) <- rownames(swiss) > all.equal(x, x[1:10]) [1] "Names: Lengths (47, 10) differ (string compare on first 10)" [2] "Numeric: lengths (47, 10) differ" which is

Re: [Rd] all.equal() improvements (PR#8191)

I'm "happy" to have found the first problem myself: 'Matrix' doesn't pass R CMD check anymore with the change I had committed: Basically because of this: > all.equal(cbind(1:5), matrix(1:5, 5,1, dimnames=list(NULL,NULL))) [1] "Attributes: < Names: Lengths (1, 2) differ (string compare on fi

Re: [Rd] R crash with complex matrix algebra when using EISPACK=TRUE

Try valgrind. That is reporting use outside arrays in rg, that is the non-complex case of eigen(). Otherwise, using gctorture(TRUE) will help precipitate the error. On Mon, 2 Jan 2006, Ole F. Christensen wrote: > > Dear subscribers of R-devel > > I am experiencing that R crashes (further detai

Re: [Rd] all.equal() improvements (PR#8191)

I've now finally finalized my work on a subset of Andy's propositions, and committed it to R-devel. The current change doesn't show in our own checks and examples, but may well in other people's package checks. For this reason, I've also added a line to the 'USER-VISIBLE CHANGES' part of the NEWS

Re: [Rd] Wish list

I very much share Duncan's concern that research in statistical software should move ahead, and contribute to some of the exciting new uses of data we see. R is the most striking success in statistical software over the last decade, in terms of the variety and quantity of statistical technolog

[Rd] R crash with complex matrix algebra when using EISPACK=TRUE

Dear subscribers of R-devel I am experiencing that R crashes (further details are given below) in some complex matrix calculations when EISPACK=TRUE has been specified in eigen(). I discovered the behaviour some months ago just after the release of R-2.2.0, and it has been lying on my desk since
