Again me. I want to plot the numbers on the bars of a barplot. This can be done using hist function when setting the label argument true (i.e. data <- c(1,2,3,4) hist(data, labels=T) When I try this using barplot I get an error: > barplot(summary(data), labels=T) Error in axis(if (horiz) 2 else 1, at = at.l, labels = names.arg, lty = axis.lty, : formal

Sorry for the question, but I really cannot find the right search terms to find an answer.. I have a data frame with strings in some of the columns. I want to know all the rows where the strings in both columns are equal. How do I do this? Thanks, Bernd [[alternative HTML version deleted]]

Hi there, I am looking for R-packages that can help me visualize properties on nucleotide sequences. I want to display sequences in the 1-100K base range as lines and plot features above and below those lines. Any ideas would be welcome. Thanks, Bernd

Hi, I am new to R and couldn't find any information on how to handle my table data that I just read in the way I want to use it.. I read in a table from a file: x <- read.delim("filenam", header=TRUE) one column (x$label) hold the class labels. Another holds some values (x$val). I want to calculate summary statistics for different classes. How would I do this? Thanks, Bernd

Hi there, I want to run an R script on a cluster with qsub. Obviously I don't want to display any X window, but I want use png() or something else to write out images. Unfortunately I get the following error message: > png(filename = " ALL.png", width = 480, height = 480, pointsize = 12, bg = "white", res = NA) Error in X11(paste("png::", filename,

Hi, I have a few hundreds files with numerical information of different length but with the same column structure. I use the following code to get summary statistics fplist <- list.files(pattern=".*analysis") for (fp in fplist){ x2 <- read.delim(fp) summary(x2) } Summary gives something like: summary (x2) V1 V2

Dear all, I am new in R so please forgive the "dumb" question... I am used to work with Mathematica where it is possible to display a 2D array as a collection of shaded squares. The gray level there represents the value of the array element. It is basically a projection of a 2-dimensional histogram. After a lot of reading I still haven't found that kind of function. I would be

Dear all I have a problem with assigning my own labels to the axis of a plot. I want to substitute the given labels e.g. 1,2,3,... with a vector of values and strings e.g. "12.23", "1.34", "245,5", "Result". B.t.w. how do I rotate these labels so they don't overlap???? I want to use the image function to plot. Thanks for your kind help. Bernd

Hi there, I have something that appears to be a factor called drug: Typeof(drug) => Integer As.numeric(drug) gives a long list Levels(drug) gives a long list, too. Now I want something like the summary function does: I want to count how often each level occurs in the given vector. My problem is that summary gives me a list with counts that is incomplete and adds the

Hi, I would like start R in BATCH mode and submit my own parameters. Or in other words, I would like to specify variables from the command line and execute a script using those. I have been looking at commandArgs and calling R from the command line under bash: R CMD BATCH --no-save --args -filename="$filname" -- r-test.R r-test.Rout The problem here is, if $filename contains

hi all I''m running background tasks using BJ 1.0.1 (gem version). On some requests, the tasks are executed as expected. On others, I get the following error: RuntimeError (no bj found in ["/u/apps/igniter/releases/20080408205801/ script", "/bin", "/usr/bin", "/sbin", "/usr/sbin"]): when it runs, it runs fine but does anyone know what

Hi, and another interesting bug report, where I'm not sure what the correct behaviour of openssh should be.

Hello, I would like to increase the number of iterations for running a Buckley-James regression model in the rms package, but something is apparently syntactically wrong. The following code initially is exactly as it appears in the help page (which runs successfully), then a "failure to converge" message (resulting from specifying an 'identity' link argument, the error message

I am cleaning up the rms package to not export functions not to be called directly by users. rms uses generic functions defined in other packages. For example there is a latex method in the Hmisc package, and rms has a latex method for objects of class "anova.rms" so there are anova.rms and latex.anova.rms functions in rms. I use:

1) dmatrix1<-function(n,p,rho,sigma,k){ muvec1=zeros(1,p) truep<-as.matrix(c(3,1.5,0,0,2,0,0,0)) A=eye(p) for(i in 1:p){ for(j in 1:p){ A[i,j]=rho^(abs(i-j)) X=mvrnorm(n,muvec1,A) y=X%*%truep+as.matrix(rnorm(n,0,sigma)) Y=X[1:k,] w=y[1:k] Z=X[(k+1):n,] z=y[(k+1):n]}} return(list(X,Y,w,Z,z)) } I made this code which performs

Hello, Is it possible to adjust the level of the denoiser ? In an old beta, before you change the aggressiveness of the denoiser, it works very well with the noise of a car, a road etc... but not now. The AEC too works very well in a old beta, but now, I think there is a problem... I have tested it with the same sound card (WB 16000). In any case, your project is the best VOIP library in this

Hello, I recently measured the distances ndist[0][nb_subvect-1] which are used to make the decicion, which codebook entries are to be used in libspeex/cb_search.c (function split_cb_search_shape_sign). For that I took a couple of audio books (all german speech), downsampled the tracks to 8kHz and encoded them with "speexenc -n --bitrate 15000 ..." (I used svn revision 11825). Usually,

Hello, just to make sure I haven't gotten anything wrong: In cb_search.c (function split_cb_search_shape_sign) after all that searching nb_subvect CB entries are being written into the stream. These are all taken from the same codebook. If I wanted to, I could just change their order, couldn't I? Because important is only the linear combination of them all together, which I keep
