similar to: Tweaking my plot of matrix as image

Hello, I know this must be a very simple problem, but I can't work it out from the documentation that is available. I've got a list of data I would like to plot (the weights of a single neuron that was trained using the neural package). The problem I'm encountering is that this set of weights, are in the form of a list. > network$weigth[1] [[1]] [,1] [1,]

Hello, I'm having more trouble with interfacing with C code. I have a function in C that will return the result of its computation as 3 arrays. The signature of the function is as follows: void lorenz_run(double x0, double y0, double z0, double h, int steps, double *res_x, double *res_y, double *res_z) The function works, as I've tested it from within C itself and the results

Hello again list, I thought I'd start a new thread, seeing as it's completely different from my previous question. Some functions I have written require many parameters, and so do not fit nicely into an 80 column width display. This is usually avoided, by spreading that particular statement over a few lines. This is something that I do in Matlab with the following: myFunc(

Hello, I would like to make a plot (preferably lines, but points will do too), where the line segment changes color depending on the value of the y-axis. For example, let's suppose the y-axis range is from -1 to 1. Points close to -1 would be colored blue, while points close to 1 will be colored red. Points in between will be varying degrees of blue/red depending on how close they

Greetings list, I've just swapped from the "neural" package to the "nnet" package and I've noticed that the training is orders of magnitude faster, and the results are way more accurate. This leads me to wonder, what training algorithm is "nnet" using? Is it a modification on the standard backpropagation? Or a completely different algorithm? I'm

Greetings list, I'm currently in the process of migrating some Matlab code to R. It's going well, but I'm running into trouble with plotting. There are a few questions I have. 1) Is there any way to do a 3D line plot in R? This would be what the Matlab function plot3 does. 2) I would like to create 3 separate plots. With Matlab, this is done by doing ... figure; plot...

Hi all, I have a x, y matrix of numbers (usually ranging from 0 to 40). I need to group these numbers and assign a color to each group (for example 0 to 15 - Blue, 16-30- Yellow, and 31-40- Red). Then I need to draw a rectangular matrix which contains X x Y boxes and each box has the corresponding value from the input matrix and is also colored according to which group (i.e red, yellow,

Hello list, Is there any way to perform a block comment in R? In C++, anything in between a /* and */ is considered a comment, and it allows programmers to comment out chunks of code for testing and debugging. Is there such a feature in R? Cheers, Wee-Jin

Dear all, I am trying to make a series of waffle plot-like figures for my data to visualize the ratios of amino acid residues at each position. For each one of 37 positions, there may be one to four different amino acid residues. So the data consist of the positions, what residues are there, and the ratios of residues. The ratios of residues at a position add up to 100, or close to 100 (more on

Dear list I need to see the code behind a function. I used to be able to see the code behind a function by typing e.g. mean(). Now I get the error message: Error in mean.default() : argument "x" is missing, with no default. Please advise.

Dear lister, I would like to now if there a universal way to writing a character vector to a file in UTF-8 encoding? By " universal", I mean a way which works under Linux, Windows and Mac. Thanks in advance! -- Ronggui Huang Department of Sociology Fudan University, Shanghai, China

Hi Collective users of Samba, (does has a nice ring to it eh?) Recently I found a my samba server being infected by win32 viruses. Though it does not affect the server in any way, I do find them to be an annoyance. I understand also that I can perform "veto" of files like *.exe in smb.conf but find that to be a wee bit restrictive. There are some users who stores valid executables in

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,

The OpenDJ is for user authentication and also user profile. Understand that Samba AD is unable to delegate authentication to an external source.

Hi, I finally came up with a nice colored matrixplot, using the color2D.matplot function of the plotrix package. But I can't assign xtics and ytics to this plot. I made sure that the matrix has correct colnames() and rownames(). Here's what I do: a=matrix(1:16, 4, 4) colnames(a) <- c("X1", "X2", "X3", X4) rownames(a) <- c("Y1",

I am using color2D.matplot to plot a matrix about 400 by 200. The values in the matrix are 0:5 and NA. The resulting plot is not color, but shaded b/w. I tried to figure out how to add colors, I would like something like c(blue, green, red, cyan, green) #example motifx <- matrix(NA, nrow=100,ncol=20) motifx[,1:5] <- 1 motifx[,6:10] <- 2 motifx[,11:15] <- 3 motifx[,15:19] <- 4

I look after an x4500 for a client and wee keep getting drives marked as degraded with just over 20 checksum errors. Most of these errors appear to be driver or hardware related and thier frequency increases during a resilver, which can lead to a death spiral. The increase in errors within a vdev during a resilver (I recently had three drives in an 8 drive raidz vdev "degraded")
