Hello R users & R friends, I just want to ask you if density() can produce a confidence interval, indicating how "certain" the density() line follows the true frequency distribution based on the sample you feed into density(). I've heard of loess.predict(loess(y ~ x), se=TRUE) which gives you a SE estimate of the smoothed scatterplot - but density() kernel smoothing is not the

Dear R friends, here I write again about the wilcox.exact() problem. I want to compare two sets of categorical data, and in one case it says "negative length vectors not allowed", and in the other one I get the error "cannot allocate vector of length ...". On http://rapidshare.com/files/298621893/wilcox.exact_trouble.Rdata.html you can download the data that cause the

Hi, I have a curious problem with speex. As long as I'm talking, it takes about 2-5% of my CPU. This seems ok. But as soon as I stop talking, CPU utilization rises to about 30-45% and stays there until I start talking again. I compiled speex from source and use it with these settings: - Preprocessor: Denoiser = ON, AGC = ON - Encoder: ABR = 15000, DTX = 1, Mode = narrowband, Rate = 8000 Hz.

Dear r-helpers! How can I integrate other distances (in the form of a dist object) into function metaMDS? The problem: metaMDS needs the original data.frame for the calculation and only the default distances of function vegdist are allowed. Any suggestions are greatly appreciated!

Dear useRs, I search for a possibillity to plot stacked bars at specific x positions. I tried and tried, but the only way i got something adequate was by using lowlevel plots segments(). That is quiet ok, but will not please eyes without a lot of par() lines. dh<-data.frame(longitude=abs(rnorm(5)),deers=abs(rnorm(5)),humans=abs(rnorm(5))) plot(dh$longitude,apply(dh[,2:3], 1,

Dear R-experts, this is not a direct R-problem but I hope you can help me anyway. I would like to minimize || PG-I || over P, where P is a p x p permutation matrix (obtained by permuting the rows and/or columns of the identity matrix), G is a given p x p matrix with full rank and I the identity matrix. ||.|| is the frobenius norm. Does anyone know an algorithm to solve such a problem? And if

Dear all, I have a problem with the function read.xls from the gdata package, error message see below. Two examples: First, I try to read my data, which does not work; Secondly, I tried the example code/data with the Iris data, which worked Any idea?

K-means recluster data with given cluster centers Dear R user, I have several large data sets. Over time additional new data sets will be created. I want to cluster all the data in a similar/ identical way with the k-means algorithm. With the first data set I will find my cluster centers and save the cluster centers to a file [1]. This first data set is huge, it is guarantied that cluster

Hello, I have a dataframe containing various time series (not time series objects though!)with hourly time steps. I?d like to perform ccf for I need to know the correlation factors for different lags. Here is an example: x<-as.POSIXct(c("2008-12-25 16:00:00", "2008-12-25 17:00:00", "2008-12-25 18:00:00", "2008-12-25 19:00:00", "2008-12-25

Moika, Overnight, I migrated my user-mails from uw-imap to dovecot-maildir. I used the uw2dovecot.pl script to convert all mails and changed exim, too. Receiving mails works fine allready, but nobody can access the usual subscribed folders with thunderbird. Via "subscriptions" I can find the converted folders in a folder called "_" (underline). People getting mad about me

Dear R users I would like to group my barplot graph (see example on the R help link). The proposed R code, adding individual bars to the plot, looks really overwhelming. My specific dataset just consists of five groups and three different levels within each groups (the individual bars). The .txt file is read as matrix (horizontal: group, vertical: levels). The R trellis barchart (function

Hi Mark, the documentation (section 3.2.1) states: "The single that will affect the CPU usage of Speex the most is whether it is compiled for floating point or fixed-point. [...] On the x86 architecture, floating-point is generally faster, but not always. " And: "Until the VBR feature is ported to fixed-point, you will also need to configure with ?disable-vbr or define

Dear R friends, I want to compare two datasets and I get the message Error in .Call("cpermdist2", ma = as.integer(m), mb = as.integer(col), : negative length vectors are not allowed after specifying the exact test. I'm using the exactRankTests package. Do you suggest me using the coin library, or is there anything "wrong" with my data? Kind regards, David --

Dear r-helpers, I estimated a generalized additive model (GAM) using Hastie's package GAM. Example: gam1 <- gam(vegetation ~ s(slope), family = binomial, data=aufnahmen_0708, trace=TRUE) pred <- predict(gam1, type = "response") vegetation is a categorial, slope a numerical variable. Now I want to assess the accurancy of the model using k-fold cross validation. I found the

Hi Jeff, Hi Jean-Marc, I first modified the FPU control word to raise an exception whenever a denormal is used. Then I used the debugger to locate the exceptions and added VERY_SMALLs where they seem to fit well. Although I got CPU usage as low as 10%, I seriously lack knowledge of how things work inside speex. So just changing some code is not the best idea for me. My second attempt was to

Dear list, I am looking for an implementation of random rotation matrix generation in R to do a rotation test: I want to use the matrices to create random multivariate normal matrices with common covariance structure and mean based on an observed data matrix. The rRotationMatrix-function in the mixAK-package is an option, but as far as I can tell I need to draw rotation matrices with determinant
