Time series in R
The help pages of R-1.2.2 include several pages on various time series functions, but when I try to use these functions they appear not to be available .... am I missing something obvious, or are these functions not yet built?

Fwd: mgcv 1.4 on CRAN
mgcv 1.4 is now on CRAN. It includes new features to allow mgcv::gam to fit almost any (quadratically) penalized GLM, plus some extra smoother classes. New gam features ------------------------- * Linear functionals of smooths can be included in the gam linear predictor, allowing, e.g., functional generalized linear models/signal regression, smooths of interval data, etc. * The parametric

R on the Zaurus link
Hello All, The link to the binary & installation instructions (tar.gz binary not an ipk I'm afraid) is as follows: http://students.bath.ac.uk/enpsgp/Zaurus/#R It eventually dawned on me that the WORDS_BIGENDIAN define (or lack thereof) was causing the problems (after testing ieee NaN compliance that is). When cross-compiling it's probably fair enough that the configure script

R on the Zaurus
Hello All, I have a working port of R on my SL5500. I've not tested the X windowing support yet, but was more concerned about the accuracy of the fp emulation. The following is the result of the test which Stuart Leask recommended I should try: Mandrake 8.2 > x<-NA > is.na(x) [1] TRUE > x+1 [1] NA > 2*x [1] NA Zaurus OZ3 > x<-NA > is.na(x) [1] TRUE > x+1 [1] 1

R on the Zaurus (the return)
Hello All, I read in the archives that someone managed to compile R but that there were problems with the fp performance, specifically the handling of NaNs. Could someone please explain the problem to me and how to test whether it is occurring. I have just compiled R for the Zaurus 5500, and want to see whether it works or requires tweaking. Regards, Simon

gaussian family change suggestion
Hi, Currently the `gaussian' family's initialization code signals an error if any response data are zero or negative and a log link is used. Given that zero or negative response data are perfectly legitimate under the GLM fitted using `gaussian("log")', this seems a bit unsatisfactory. Might it be worth changing it? The current offending code from `gaussian' is:

get_all_vars fails with matrices (PR#13624)
Hi, According to the help file for model.frame/get_all_vars, the following should produce the same output from both functions, but it doesn't... > dat <- list(X=matrix(1:15,5,3),z=26:30) > model.frame(~z+X,dat) z X.1 X.2 X.3 1 26 1 6 11 2 27 2 7 12 3 28 3 8 13 4 29 4 9 14 5 30 5 10 15 > get_all_vars(~z+X,dat) [1] z X <NA> <NA> <0

naresid.exclude query
x <- NA na.act <- na.action(na.exclude(x)) y <- rep(0,0) naresid(na.act,y) ... currently produces the result... numeric(0) ... whereas the documentation might lead you to expect NA The behaviour is caused by the line if (length(x) == 0L) return(x) in `stats:::naresid.exclude'. Removing this line results in the behaviour I'd expected in the above example (and in a

mgcv 1.5-0
mgcv 1.5-0 is now on CRAN. Main changes are: * REML and ML smoothness selection are now available. * A Tweedie family has been added. * `gam.method' has been replaced (see arguments `method' and `optimizer' for `gam') For other changes see the changeLog.

Cubic splines in package "mgcv"
re: Cubic splines in package "mgcv" I don't have access to Gu (2002) but clearly the function R(x,z) defined on p126 of Simon Wood's book is piecewise quartic, not piecewise cubic. Like Kunio Takezawa (below) I was puzzled by the word "cubic" on p126. As Simon Wood writes, this basis is not actually used by mgcv when specifying bs="cr". Maybe the point is

Cross-compiling packages for (ARM) Zaurus ideas and tips?
Hello All, A bit of a long one (background mainly), this is really just a request for some ideas. I ported R 1.7.x for use on the Sharp Zaurus (& iPAQ, simpad, yopy, etc.) some time ago and have just ported 1.8.1 but had never quite realised that you actually need to install some packages to make the system useful (I don't use R, I did it as a favour and of course for the fun of it). I

Fwd: Re: residual checking for GAM (mgcv)
The plots look reasonable to me. The plot of residuals against linear predictor always looks scary when many of the fitted values are very close to zero, so I tend to look at residuals against sqrt(fitted) in such cases. I don't think that the presence of the zero curve is a reason to reject the model --- it's easy to produce such plots by fitting a completely correct model to simulated

Users Become Nobody
Hello We recently upgraded samba on our UNIX to version 1.9.18p1 partly because sometimes users would become NOBODY rather than their username and this was screwing up the permissions of the files they save or try to read. But this version is doing it too. It seems to be random. Every so often Ill run smbstatus and have a look and a handfull of users are logged on as NOBODY. These clients are

[Fwd: REML - quasipoisson]
Hi Greg, For quasi families I've used extended quasi-likelihood (see Mccullagh and Nelder, Generalized Linear Models 2nd ed, section 9.6) in place of the likelihood/quasi-likelihood in the expression for the (RE)ML score. I hadn't realised that this was possible before the paper was published. best, Simon ps. sorry for slow reply, the original message slipped through my filter for

R-2.0.0 on ARM (Sharp Zaurus)
Hi All, I've recently dusted off my cross-compiling hat and decided to add R to the OpenEmbedded build environment (this is used to build the OpenZaurus/Familiar distributions for the Zaurus/iPAQ amongst other things - I note there's also work underway to add the Psion 5mx etc. to OpenEmbedded). OpenEmbedded builds now use -soft-float which makes floating point operations something like

Recombining Mon and Year values

But I need to recombine them so I can graph mon-year in order but when I recombine I lose the month order and the results are plotted alphabetical.

Lazy-loading db setup in the R build process
Hi All, I have read the article on lazy-loading in the September R news letter, and think I have at least a vague grasp on what is happening. Am I right in thinking that, assuming I were using the same packages, I could copy the .rdb & .rdx files from one installation of R (2.0.0) to another? I ask this as I'm trying to cross-compile R (for ARM), and need to use R itself to perform the
