Dear R-users, I found a strange problem working with products of two matrices, say: a <- A[i, ] ; crossprod(a) where i is a set of integers selecting rows. When i is empty the result is in a sense random. After some trials the right answer (a matrix of zeros) appears. --------------- Illustration -------------------- R : Copyright 2003, The R Development Core Team Version 1.8.0

I am pretty pleased with baselines I fit to chromatograms using the runquantile() function in caTools(v1.6) when its probs parameter is set to 0.2 and its k parameter to ~1/20th of n (e.g., k ~ 225 for n ~ 4500, where n is time series length). This ignores occasional low- side outliers, and, after baseline subtraction, I can re-adjust any negative values to zero. But runquantile's

Dear all, you can find below my solution for sliding a window. Please find below the code for the two alternatives and the benchmarks.     install.packages('caTools') require(caTools) do_sliding_for_a_window_duty_cycle <- function(DataToAnalyse,  windowSize) {   data<-DataToAnalyse   out <- numeric()   elements<- numeric()   if (length(data[,1]) >= windowSize){       for

Hi, A new version of "caMassClass" package was released today. The package contain pipeline for processing and classification of protein mass spectra data. The main change is off-spinning from the library collection of generic functions into a new package "caTools". This package, which might be useful to broader group, is much smaller than "caMassClass" and has fewer

Hi, I tried to install the caTools package manually from the main R Project website and I get the following error message when typing library('caTools') Error in library("caTools") : 'caTools' is not a valid package -- installed < 2.0.0? What am I doing wrong? Also, why is this package not available in the list of packages for direct installation from the R

Dear list, I am using R.2.11.1 version on a PC. I downloaded successfully gplots_2.8.0 but I could not find where to download caTools > library("gplots") Loading required package: caTools Error: package 'caTools' could not be loaded In addition: Warning message: In library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc = lib.loc) : there is no package called

Hi there, using cbind with a numeric and raw argument produces an incorrect result. I've posted some details below, kind regards, Mike. e.g. > cbind(0, as.raw(0)) [,1] [,2] [1,] 0 6.950136e-310 A longer example shows that the result is not a rounding error, is not consistent, and repeated applications get different results. > cbind(0, as.raw(1:10))

For what it's worth the following patch fixes that particular problem on my system.? I have not checked very carefully to make sure this does not cause other problems, but at a high level it seems to make sense.? In this particular part of the code I believe `mode` is taken to be the highest type of "column" encountered by `ctype` and based on conditionals it can (I think) be up to

Thanks Brodie, that's some nice detective work. If someone wanted to grant me access to Bugzilla, I'll be happy to post the bug and patch there (with your permission Brodie?) and help this bug get fixed. Mike.

Hi, I suddenly started getting strange errors while working on my caTools package: >RCMD install C:/programs/R/rw2011/src/library/caTools ...... preparing package caTools for lazy loading Error in file(file, "r", encoding = encoding) : all connections are in use Execution halted make: *** [lazyload] Error 1 *** Installation of caTools failed *** I searched

Dear All,   I have the following example:   a <-matrix(c(1:100),ncol=10) b <-matrix(c(2,4,6,8,10,12,14,16,18,20))   trapz(b,a)   will give me a result of 99, which it seems to me is the AUC of the 1st column only. Is it possible to get the AUC results by columns of "a" using the same "b" values in the calculations as opposed to just generating the result for the 1st

Hello I have a 3.5 million elements numeric vector x. I'm trying to calculate the rolling std dev of the previous 144 elements. rsd144<-runsd(x, 144, center=0, endrule="NA") this crashes R (ie on the console disappears and the Rgui.exe process is not there anymore) with smaller vectors, the crash does not occur. regards, [[alternative HTML version deleted]]

Hi, A minor announcement. I just added two functions for reading and writing GIF files to my caTools package. Input and output is in the form of standard R matrices or arrays, and standard R color-maps (palettes). The functions can read and write both regular GIF images, as well as, multi-frame animated GIFs. Most of the work is done in C level code (included), so functions do not use any

I had installed de "gplots" package and then I loaded the library but the package did not work.

Everyone, I've got code in my package that uses LogitBoost from the caTools package. caTools does not have a namespace. My package also uses loads RWeka, which has a namespace, and also has a function called LogitBoost. After loading both packages, how can I be specific about running the version from caTools (since caTools:::LogitBoost won't work)? Thanks, Max

Hi, I was lately debugging parts of my 'colAUC' function in caTools package, and in a process looked into other packages for calculating Areas Under ROC Curves (AUC). To my surprise I found at least 6 other functions: * wilcox.test * AUC from ROC package, * performance from ROCR package, * auROC from limma package, * ROC from Epi package, * roc.area from verification

R gurus, On Aug 20, 2002, I asked in R-help about calculating a running 5-day median on a large matrix. Thanks to Martin Maechler <maechler@stat.math.ethz.ch> and Ray Brownrigg <Ray.Brownrigg@mcs.vuw.ac.nz> for responding. I ended up writing C code (and an R interface) to do it, which is about 1000x faster than the naive method! (72s became .09s on a 223 x 520 matrix). I added a
