similar to: print-show-display a matrix

I'm using 1.9.0 on Windoze 2k and I created a numeric matrix and used colnames() to give it some column names, but if I try to select a column using matrixname$validname I get a null return but if I use matrixname[,4] it works fine. Looking at the help I think this is because a matrix is not a recursive structure and I think it's saying I shouldn't be surprised nor attempt this.

For the 1000 simulations, a matrix will be generated each time. And, I need to choose the first row of the generated matrix. The following loop doesn't work though: for (i in 1:1000) { aval[i]<- matrixname[1,] } Any solution? thanks!

Hi, I want to write a matrix (n*m) in a file (Text file) such that the file will be as Result file (below). I use the below command but it write all numbers in one column, > write(paste(matrixname),file="test.txt",append=TRUE) how can I do this? Result file: 5 5 -1 -1 -1 -1 8 8 2 7 6 5 6 6 8 2 7 5 Matrix: [,1] [,2] [,3] [,4] [,5]

Hello everyone, Could you please help me find out if R supports matrixes inside matrixes? This is what I would like to do I have an area map of humidity per km. I would like at every cell to keep also information about the height of this area, the current temperature etc. Is something like that supported? I would like to thank you in advance for your help Best Regards Alex

Hi, I would like to store some text and decimal values in the following form: name dec.val dec.val ... dec.val name dec.val dec.val ... dec.val ... name dec. val dec.val ... dec.val To do so, I created a matrix of the necessary size (x row per y cols) with the command matrixname <- matrix(0,x,y) and proceeded to fill in the matrix with information drawn from a data frame. The

Dear all I am using color2D.maplot to map some matrixes to plot. everything works fine. It seems that when my matrix contains only the same value color2D.maplot returns the following error: color2D.matplot(estimatedsr,redrange=c(0,1),greenrange=c(0,.5),bluerange=c(0,.5),xlab="x",ylab="y",main=sprintf('Estimated'),show.legend=TRUE,show.values=TRUE) Error in rgb(reds,

Dear all I have two 10*10 matrixes and I would like to compare theirs contents. By the word content I mean to check visually (not with any mathematical formulation) how similar are the contents. I also know edit that prints my matrix in the scree but still one edit blocks the prompt to launch a second edit() screen. What is the best way to compare these two matrices? I would like to thank you

This topic came up some time back and I pretty much ignored it, but the "itch" came back to find out why. Searching through the FreeNX/knx list came up with the reason sessions did not come up full-screen even though the session definition was set to fullscreen. Apparently there is an oversight in /usr/bin/nxnode, the script is never retrieving the fullscreen flag from the parameters

Hello I would like to calculate a weighted line integral. The integral is calculated by the cells that this lines trasverses (the small cells belong to matrix (m*n) that represent the value that a specific area has. I need to calculate the weights by finding out how much the line touches or impinges inside a cell. The weight is less if a line just touches one of the four edges of a square

Hey, I've noticed some strange behaviour in the latest wine versions 1.2rc-x. At 1.2rc-1-3 when I installed games like Guild Wars or Runes of Magic the first start in fullscreen turned the birghtness level of my laptop to 100%. (having a Sony VGN-NR21S with an Nvidia 8400M-GT). I'm setting the brightness level with smartdimmer (nvclock package). When I enter "smartdimmer -s

Hi r-help, I have a weird problem. When I plot anything, say plot(1:10), a plot window opens but it's empty. It looks just like this: http://i.imgur.com/9uqO6.png I have to resize the window, either by clicking the fullscreen icon on the menu bar, or by dragging the borders. Then the plot is shown, but strangely in the original size of the window, where it was before the resize:

I've currently got the nx-1.5.0-1.centos4.i386, freenx-0.5.0-8.c4.noarch, and nxclient-1.5.0-141.i386 packages installed on a couple of CentOS 4 update 3 systems and I'm getting the same results on all of them. I got the new version of freenx via "yum update" and it appears to have "broken" fullscreen mode. The connection config file I have been using does have the

Hello everyone I need some advice if the following might be easier implemented. There are n matrixes each matrix needs to calculate one value for the rest n-1 matrixes (but not for itself). I implemented this one by two nested loops for (i in c(1:length(CRX))) { for (j in c(1:length(CRX))) if (i!=j) # where i and j are the two indexes. If i==j then is the same matrix.

Need to test a monitor attached to a running server, so I'm looking for an application/utility to display a large color graphic. This must be possible to do without X because a splash screen comes up when this system boots. The best graphic to display obviously would be some kind of fullscreen test pattern. Anyone know where to get that? tia, ken

Hello all I would like to ask your help use mapply. I have a function called findCell that takes two arguments(x,sr) where x is a vector of size two (e.g x<-c(2,3) and sr is a matrix. I would like to call many times the findCell function (thus I need mapply) for different x inputs but always for the same sr. as x is a vector of size two (two cells) I want to pass inside inside the following

Dear all, I am using ggplot with geom_tile to print as an image a matrix  I have. My matrix is a squared one of 512*512 cells.  The code that does that is written below > print(v + geom_tile(aes(fill=dB))+ opts(axis.text.x=theme_text(size=20),axis.text.y=theme_text(size=20), axis.title.x=theme_text(size=25) , axis.title.y=theme_text(size=25), legend.title=theme_text(size=25,hjust=-0.4) ,

I worte in my last mail that when I ue compiz git fullscreen videos are no longer ontop of the gnome-panel... that means that the gnome-panel is still visible while playing the video in fullscreen. The commit which I said may caused it has nothing to do with it compiz does not build if I revert it). again with older compiz and metacity it works fine. (now I am running 20070316). Anyone else wiith

Hi all, this error is almost certainly due to a misconfiguration while using tools/winebuild, but every time I update my version of Wine, my fullscreen game (Hoyles Card Games 2001) refuses to work fullscreen anymore :( NB. My current Wine build (LinuxMint) is about 0.9.44 or so, which is the working one. Many of my distro's built in versions of Wine have all worked fullscreen, it is only

Hi, I've been trying out nouveau for a while now and I must say I'm impressed. Performance in KDE4 in general seems better than the nvidia blob; way to go! There are a couple of annoyances though: XV in fullscreen doesn't work. I'm running in composite mode, and non fullscreen video works well enough. Going fullscreen in e.g gmplayer gives me: [ws] Error in display. -0.005 ct:

Hi all, I'm looking for a way to force a certain window on my desktop to go fullscreen. The window in question is from Enemy Territoy, it tries to go fullscreen, but for some reason doesn't work, and stay always redirected with obvious framerate slowdown (keep 6-7 fps average on a FX 5200). I was thinking something like xwinwrap, which you can call a process and force his window to
