similar to: Cross-compiling packages for (ARM) Zaurus ideas and tips?

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

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

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

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

For what it is worth, here are my experiences. When I first got my zaurus I compiled R version 1.4.0 for the it. It took some time to do, but managed with the skiffclusters at familiar.org. (libf2c was the hardest part). Compilation should be easier now that there are onboard compilers but I haven't tried. I thought this would be neat to have in the classroom. (It did get one student to buy

Dear All, I have a working (in so far as NAs are handled correctly) version of R running on the Zaurus. The problem was not ieee 754 compliance but rather the fact that the configure script did not realise that the Z had a bigendian processor. I'll post a link, etc. tomorrow on the Zaurus forum for those who may be interested (http://www.zaurus.com/dev/board/) in downloading a copy.

Just wondering if there are any Zaurus owners out there using there zaurus as a voip phone?? I'm trying to decide which on to buy. The sl-6000 is perfect for phone use from what I've read, but it's not very pocket friendly (http://www.sharpusa.com/images/hpc_SL6000_pic1.jpg) The clamshell models (http://conics.net/shp/pda/zaurus-sl-c700/sl-c3000.html) are much nicer but would

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

Ah, but the interesting thing is that they are coming out with a 'clam' version like the 5MX. Details are limited at the moment, but that could mean the combination of 5MX usability with a supported linux distro. I am drooling in anticipation. Sounds like a "I've finally finished my PhD and deserve a treat" situation to me :) Dave On Thu, Mar 06, 2003 at 09:17:20AM

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

Hi I am a new R user and I did try elrm package to do Exact Logistic regression for my dataset ( about 170 patients with a binary dependent variable against age and 6 other binary covariates), I did not have n column because it was about individuals, I made n column with 1 for each individual, here is my code and result: > > #### Libraries needed #### > >

I'm using rsync to mirror my Sharp SL-5500 Linux PDA home directory to my Linux desktop over a TCP/IP-on-USB link. I'm running the following command as root on the 5500: /home/QtPalmtop/bin/rsync -av /home/zaurus \ 192.168.129.1::zaurus I'm running the rsync server out of xinetd. I have verified with 'ps' that the server, when it starts, is running as root. The files are

I've got a data frame which I've split by a factor, creating a list of dataframes which I have then done various operations on individually. I next want to recombine the resulting dataframes (still held in a list, still with the same number of columns with the same names) and there does not appear to be a `good' way to do this - at the moment, I'm using a for-loop with the rbind

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.

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
