#I have a dataset with two factor. I want to combine those factors into a single factor and count the number of data values for each new factor. The following gives a comparable dataframe: a <- rep(c("a", "b"), c(6,6)) b <- rep(c("c", "d"), c(6,6)) df <- data.frame(f1=a, f2=b, d=rnorm(12)) df # I use the 'interaction' function to combine

Dear all, I am not sure what I am doing wrong, but I have some unexplained behaviour when saving a lattice graph including text to a pdf file. The text seems to move around. It must have something to do with the way coordinates are set in devices other than jpg. Any suggestions would be helpful Willem Here is some example code setwd("c:/willem/research/misc") today <-

Hi all, I am trying to convert a data set of physician death codings (each individual's cause of death is coded by multiple physicians) from long to wide format, but the "reshape" function doesn't seem to work because it requires a "time" variable to identify the sequence among the repeated observations within individuals. My data set has no order, and different

I have been using PXELINUX, with "LOCALBOOT 0" when wanting to boot from disk, for many years. Now on new Dell Optiplex 990 machines, PXE boot with "LOCALBOOT 0" hangs after message Booting from local disk... without the expected "Exiting PXE" message. I tried "LOCALBOOT -1" and some other values also, none seemed to work. I tested SYSLINUX 4.04.

Hello, I try to compile player_example.c from http://downloads.xiph.org/releases/theora/libtheora-1.1.1.zip in Visual Studio 2008 on Windows XP. I built and added to the project libogg-1.3.0, libtheora-1.1.1, libvorbis-1.3.2 (http://www.xiph.org/downloads/) and SDL-1.2.15 (http://www.libsdl.org/release/SDL-devel-1.2.15-VC.zip). When I compile player_example.c Visual Studio shows: fatal error

Hello all, I'm new to R and trying to figure out how to perform calculations on a large dataset (300 000 datapoints). I have already made some code to do this but it is awfully slow. What I want to do is add a new column for each "rep_ " column where I have taken each value and divide it by the mean of all values where "PlateNo" is the same. My data is in the following

I'm having trouble debugging x86 code generated by LLVM. GDB does work with the code, but not correctly, for example, the "next" command does not skip over a function call. Here's an example. Source program gdb1.c: int x; void foo(){ x++; } void bar(){ x--; } int main(){ foo(); bar(); return 0; } commands: $ llvm-gcc -g -emit-llvm -c gdb1.c -o gdb1.bc $ llc

Hi, I want to do something like this: par(mfrow=c(7,7)) for (i in 1:49) hist(RATDACOM[SUBJNO==i],breaks=0.5+(0:6), main="",xlab="",ylab="",xaxt="n",yaxt="n") (Don't think about what RATDACOM and SUBJNO are.) I get an error Error in plot.new() : Figure margins too large. 36 histograms with mfrow=c(6,6) work. But the 36 histograms

Hi all, is there a way to extract the name of a function, i.e. do the reverse of match.fun applied to a character string? I would like to print out the name of a function supplied to another function as an argument. For example: myFunc = function(x) { x+1 } applyFunc = function(fnc, x) { fnc = match.fun(fnc) fnc(x) } Is there a way to obtain "myFunc" from the argument fnc in

Hi R-people, I have a question about lattice in general, and histogram specfically. How do you control the ordering of factors that controls the placement of the conditional panels. I have a dataset with factors that go 'Q1','Q2',"Q3','Q5' and of course I want the plot to place Question Q1 at the top and Question Q5 at the bottom of the graphical output.

>Also, 'portaudio' doesn't appear to produce a static library at all, so it doesn't appear to be possible to get a working splayer executable on Linux unless there is a 'hidden' way to get the portaudio distribution to build one. ("ldd: -lportaudio not found"). I believe splayer is only intended to be a Win32 executable. Note that it is in a directory

I have been using PXELINUX for a while and appreciate all you guys are doing! I have a couple of questions re PXELINUX: 1. I am experiencing problems with the LOCALBOOT statement on an IBM x3650. IBM mentions the following: http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5084755 I am using PXELINUX 4.04. Is this problem still attributed to some bug in PXELINUX? Right now I

Hola buenas noches, tengo un problema bastante gordo. ¿A alguno le ha dejado de funcionar las funciones pamer.fnc y mcp.fnc con la nueva versión de R? La semana pasada formatee el ordenador y ahora scripts antiguos no funcionan. La cuestión es que me precupa que no funcione el ejemplo de tutorial del autor. Os dejo un script que debería de funcionar y no lo hace

More newbie questions from me ... How do you specify multiple requires in an exec ? What I''ve tried: define cvsserve($source, $path, $user = false) { file { $path: ensure => directory, owner => root, group => root } $cvscmd = $user ? { false => "/usr/bin/cvs export $source/$name .", default =>

Hi all, Just a heads up to let you know that I've fixed up the Visual C++ project files so that libtheora and the associated experimental programs (dumpvid/encoderwin/splayer/transcoder) builds on Windows again. I also have good news and good news. The bad news is: experimental\splayer doesn't work. It compiles, but segfaults immediately when you try to play any Ogg file. The bug

Hi! I'm having some trouble with theora in windows, I would really appreciate if you could be able to give me a hand with this. First, I was not able to build theora in cygwin, because I built vorbis and ogg perfectly, but when I try to run ./configure with theora it can't find the ogg libs, if I use the --using-ogg-path = ... with /usr/local/lib it runs ok, but then it fails to compile

Dear R list, I have a recurring problem with the languageR package, specifically the aovlmer.fnc function. When I try to run the following code (from R. H. Baayen's textbook): # Example 1: library(languageR) latinsquare.lmer <- lmer(RT ~ SOA + (1 | Word) + (1 | Subject), data = latinsquare) x <- pvals.fnc(latinsquare.lmer,

I see. Here's another interesting issue: (gdb) b gdb1.c:4 No line 4 in file "gdb1.c". (gdb) step foo () at /home/mcmillan/projects/impact2/test//gdb1.c:4 4 x++; (gdb) You can see that I can step to line 4, but I can't set a breakpoint there. (I used -disable-fp-elim in the compilation). Have you seen this before? Thanks -- Ken Dale Johannesen wrote: > > > On
