Dear all, Uwe e-mailed me yesterday about the problems some time ago. I had hoped someone would have a look at our computers, but due to some unfortunate circumstances, it hasn't happened. However, it seems unlikely that it is connected to a specific piece of hardware. It could be an architecture-dependent problem though. I also had a word with those who did the installation of R, and they had some problems when tuning it for alphaev6, but it all went smoothly when tuning for alphaev56, and that is the build I'm running. This is basically the stuff I sent to Uwe yesterday. I have been testing it on three different machines: alnair, a XP1000 with a 500MHz alphaev6 processor and 619 MB RAM rukbat, a PWS500au with a 500MHz alphaev56 processor with 238 MB RAM mirfak, a DEC255/233 with a 233MHz (?) alphaev4 (?) processor with 245MB (RAM is according to top). All show the same problems consistently. I'm not using the match.arg()-approach anymore, BTW, I have moved on to some object-oriented stuff. However, some apparently related (?) problem occurs. Yesterday, I started working on some simulations I have done (with R of course! :-) ). I did exactly the same operations on rukbat and mirfak (using ESS-elsewhere while sitting on alnair), starting with the same calls, vsize=80M, nsize=800k, no-restore. I loaded a 58MB file with load, and there are a few variables with arrays of htest-objects. Then, I did as.vector(sapply(chisq5M11000, function(x) x$statistic)) to get a vector of the test statistics. Now, occasionally, it prints a nice vector with all the values intact. Occasionally, one of the entries are NULL, and then it prints a list, e.g. [[892]] X-squared 1933.637 [[893]] NULL [[894]] X-squared 1741.416 The funny thing is that when I did this sapply thing on mirfak and rukbat, it happened on at exactly the same place on the two machines. First, mirfak would produce a vector then rukbat would produce a vector, mirfak would give a list where element # 238 (if I remember correctly) was NULL, rukbat would produce a list with element #238 NULL, both would produce a vector again, both would produce a list with element #602 NULL, etc... This is pretty much what I've got now... :-) Best, Kjetil -- Kjetil Kjernsmo Graduate astronomy-student Problems worthy of attack University of Oslo, Norway Prove their worth by hitting back E-mail: kjetikj@astro.uio.no - Piet Hein Homepage <URL:http://www.astro.uio.no/~kjetikj/> Webmaster@skepsis.no -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
