Hello all, I'm now using image() to show image data (in my case dumps of SOM weights) but would like to show RGB colour data, not just single "z" colour values. I've currently been using seq() to skip 4 values, so I can show the R, G or B channels separately as "z". But is there a way I can show all three channels simultaneously as a proper colour image? Thanks, B.

Hello all, I've scoured the archives and google and I can't figure out how to amalgamate a set of vectors of differing lengths in such a way as I can calculate the mean easily. The following dummy example contains vectors of length 1, but my data has vectors of various lengths. R> test = list(); for(i in 1:5) {test = append(test, i)} R> test [[1]] [1] 1 [[2]] [1] 2 [[3]] [1] 3

Hello all, I'm using R to visualize and explore the data produced by a software system. The software generates logs for many types of events. The software runs for days on end, and can possibly generate multiple events per second. What is the appropriate time format for year, month, day, hour, minute, second, millisecond? that R can properly interpret (using zoo? or ITS?) I'll have

Hello all, I'm getting much further with my time-series work, but still getting into some problems. I'm using POSIXct time format with both date and time. I'd like to use that in an its object but It seems its only processes the date part of the POSIX time stamps: BMU_its_data <- its(data[BMUindex,2-4],dates=data[BMUindex,1]) Error in `row.names<-.data.frame`(`*tmp*`,

Hello all, I'm stuck with a strange issue with writing jpegs of plots to a folder in a loop. This works: for (step in 1:length(steps)) { jpeg(filename=paste("frame_",sprintf("%05d",step),".jpg",sep="")) plot(steps[[step]]) dev.off() } But if I use qplot to generate the plot (which is my aim): for (step in 1:length(steps)) {

Hello all, I've been using the following qplot command: qplot(pixX,pixY, data=som, geom="tile", fill=rgb) + scale_fill_identity() + opts(aspect.ratio = .75) + facet_grid(unitX ~ unitY) Now I would like to convert it into the explicit ggplot grammar, so I can remove the extras: axes, labels, background, borders, facet labels, and extra white-space around the plot. (If anyone has

Hey all, I'm working on a media-database art project that basically stores a bunch of sound and video files, which are then navigated based on meta-data. I'm not sure where to start asking these, questions, here seemed like a good start. So I was thinking I should use an open format, like ogg/vorbis/theora. I also thought, will all that coll meta-data stuff in ogg I should be able to

Hello, Sorry if anyone gets this message twice, as my mailserver may not be working. Thanks for your response. Your idea makes a lot of sense to me, but I've been unable to get seconds to work. I ended up with this format finally: "2007-10-31_16:20:22" Problem is I am unable to get it recognized as a date using timeDate(): R>

Hello It's possible that the public parameter "config file" in the new Samba Version 2.2.0 did not work? (config file = /usr/local/samba/lib/smb.conf.%G) %G is "nobody" if I don't restart the Client. And if I restart the computer it's the primary group of the user. I try it with a Win98 Client and Samba is running under SuSE Linux 7.1. Do you have any Idea what can

Hello all, I'm working on a project that uses a SOM to generate feature maps from image data. Each image is a 100x75 pixels and RGBA, so 30,000 elements per image. I wanted to observe the structure of the pixel by pixel euclidean distance (where each image is a point in 30,000 dimensional space) of my image data. Sammon's projection seems appropriate for this, though I'm a bit

Hello, I compiled rsync with the time-limit patch on my machine. But when I try to archive to a remote server I get the following error: rsync: on remote machine: --time-limit=4: unknown option Is there a way to use the time limit patch if the server doesn't support it. I would like rsync to just quit after specified amount of time and continue where it left off the next day. Thank you

Hello all, I have an older machine with an AGP GeForce N6600 Nvidia card. I recently bought a new colour calibrated monitor to replace an old CRT and I've since noticed a stark difference in the colour produced by the N6600 and my newer machines with series 5 and 7 graphics cards. The newer cards show similar B+W contrast, but colour is much less saturated on the N6600. I had been

Hello fellow R sufferers, Is there a way to perform an appending operation in place? Currently, the way my pseudo-code goes is like this for (i in 1:1000) { if (some condition) { newRow <- myFunction(myArguments) X <- rbind(X, newRow) # <- this is the bottleneck!! } } As you can see, it works but as the matrix X gets the size of a few million rows, the

I'm trying to boot nfs-root kernel using pxe. Kernel version is 2.6.28, image size - 2.3MB. tftp server works fine. The curious part: if I type the kernel image name at "boot:" prompt, exactly as it appears on the "Loading" line, everything works as expected. Does anybody have any ideas what it could be? By the way, gpxelinux exhibits the same behavior.
