Hi! I am using the fft() function the base package to transform some 1d signal. If I use this standar fucntion I get a very huge first fourier coeficient. I think this dues to the handling of the borders of the signal. Usually in fft especially in image processing the signal is simulated to be continuous by adding the signal several times periodically. My question is, is there some function

Hi! I am using R 1.8.1 and the svm of the e1071 package for classification. The problem is that I have unbalanced classes e.g. the first one is much bigger than the second one and therfore the svm is biased to the first class. If I manually adjust the class size the bias disappears. The question is then how to include this unequal class distribution to the svm (e.g. via wheights or costs)?

Hi! I've got two problems with listboxes and selection: I created a listbox, no problem. Then I bind the Button-1 of the mouse to the listbox to start some things by pressing the mousebutton.

Hi! I'm using the RODBC packages for connecting R and a mysql database. To do this, i use the function odbcConnect(dsn,uid,pwd).

Dear R-helpers: I want to calculate area under a Receiver Operator Characteristic curve. Where can I find related functions? Thank you in advance Xiao

Dear Gerrit Thanks a lot. "rbind" seems to be the right function. Unfortunately there is a shift in the x-axis (see pdf). There are 52 trapcatch values each, m and w, but m$trapcatch and w$trapcatch are shifted up to x-value 60. The follow-up lines for temp and humidity are fine. Thanks Sibylle setwd("~/Desktop/DatenLogger2017") # am Mac sks trap =

Hi, Sibylle, since you write '"mathematically" add', does barplot(rbind(m$trapcatch, w$trapcatch)) do what you want (modulo layout details)?

Hello, R-help, does anybody have already a work-around for the problem that the formula version of sunflowerplot() throws an error when provided with a value for xlab (or ylab) different from NULL: > sunflowerplot( Sepal.Length ~ Sepal.Width, data = iris, xlab = "A") Error in model.frame.default(formula = Sepal.Length ~ Sepal.Width, data = iris, : variable lengths differ

One of the few things that I miss from Splus is the ability of interactively add text and symbols to graphics that have been created by functions. I understand that the best solution in R is to create a graphic file and use external software for editing the graphic. I know what to use in the Win environment, but could anyone suggest what tools would be appropriate under Linux? Thanks Agus Dr.

We are looking to implement a code review system that will require a review of the code before it gets to production servers. I have been looking into many different options, and would love some feedback and experiences from other users. Our puppet is in a git repo. We have 3 primary environments with a branch of puppet for each of them. All of our puppet info is in the git repo

Dear Gerrit, This issue is discussed in a vignette in the car package (both for functions in the car and effects packages): vignette("embedding", package="car") .

Dear R users aim Barplot of insect trap catches (y variable trapcatch) at one specific station (variable FiBL_Hecke) from week 1-52 ( x variable week). It works well using the function tapply (sum trapcatch per week, males and females not separated), however, I intend to separate the y variable trapcatch in males and females (variable m_w: m and w) problem I used the function "add" to
