similar to: R not 'seeing' numbers?!

Hi, I have a problem using the function 'reshape' for the following dataset: input: X Y Z T.U.1 T.U.2 T.V.1 T.V.2 1.00 1.00 A 24.94 24.74 34.65 35.33 1.00 3.00 A 26.03 25.87 25.76 26.12 1.00 1.00 B 24.76 24.63 34.34 34.48 1.00 3.00 B 26.15 25.98 25.96 25.66 2.00 1.00 A 24.40 24.26 34.55

Hello everybody, it looks like the presense of some (do know know which) S4 methods for a given S4 class degrades the performance of xtfrm (used in 'order' in new R-devel) by a factor of millions. This is for classes that ARE derived from numeric directly and thus should be quite trivial to convert to numeric. Consider the following example: setClass("TimeDateBase",

Friday I enabled the inlinehint function attribute in the inliner. It mostly affects the performance of -Os compiled code. I have made some measurements on the SPEC test suite to show what it means. I made three runs of then nightly tests. The baseline represents -Os with no inlinehint: make TEST=nightly OPTFLAGS=-Os EXTRA_LOPT_OPTIONS=-inlinehint-threshold=0

Hello everyone, I have got the same problem, with the same error message. Using R 2.14.1, plyr 1.7.1, R.Studio 0.94.110, Windows XP The plyr mailing list does not provide any help until now. >require(plyr) >c(sample(c(1:100), 50, replace=TRUE))->V1 >c(rep( 1:5, 10))->f1 #variable to group V1 >data.frame(cbind(V1, f1))->DF >str(DF) >ddply(DF$V1, DF$f1,

Below are the results for the Polyhedron 2005 benchmarks compiled with llvm/compiler-rt/dragonegg 3.3svn at r182439 against current FSF gcc 4.7.3svn and 4.8.1svn. The only major bug remaining in the dragonegg 3.3svn support for gcc 4.8.x is http://llvm.org/bugs/show_bug.cgi?id=15980 which results in unresolved symbols for _iround and _iroundf in the aermod and rnflow testcases.

hi guys/gals I realize that this question must have been asked before, I sroogled and found some posts on the web on how to tweak/tune gluster, however.. What I hope is that some experts and/or devel could write a bit more, maybe compose a doc on - How to investigate and trouble gluster's speed-performance bottleneck. Why I think such a thorough guide would be important? Well.. I guess

Dear all, I am encountering some issues with my data and need some help. I am trying to run glm analysis with a presence/absence variable as response variable and several explanatory variable (time, location, presence/absence data, abundance data). First I tried to use the glm() function, however I was having 2 warnings concerning glm.fit () : # 1: glm.fit: algorithm did not converge # 2:

Hi Michael and Everyone I'm trying to connect Asterisk to a CISCO AS5350 using oh323 and I'm getting this error "reason 24 (Call ended with Q.931 cause)" I've checked the Asterisk wiki and several other resources. Please can anyone give me a hint on what the problem is I reach my wits end. Thanks Tola my config and debug Configuration of OpenH323 channel driver

Hi all, Typically I dont have issues with configuring X. However this time its an issue. I have an NVIDIA graphics card trying to do 1920x1080. If I configure the screen by hand with the nvidia config utility it works at 1920x1080. However when I reboot its 800x600. When I use the nvidia config utility to set 1920x1080 then save the xorg.conf file, and reboot (yes I copied /tmp/xorg.conf to
