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

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.

Hi, I am currently studying Decision Trees by using rpart package in R. I artificially created a data set which includes the dependant variable (y) and a few independent variables (x1, x2...). The dependant variable y only comprises 0 and 1. 90% of y are 1 and 10% of y are 0. When I apply rpart to it, there is no splitting at all. I am wondering whether this is because of the

Greetings! I'm currently gathering information that helps software in assessing the user's context. One very important such data would be the application that the user is currently working with which mostly is roughly equivalent to the name of the window that has the focus. Unfortunately I'm at a loss even about which API to ask for this information. As personally I am using compiz as

Hi, I'm trying to install the game "Aquanox" under Wine which needs DirectX 8.0. I've found a mail in the wine mailing list archive stating that wine already includes DirectX, but Aquanox keeps complaining about a missing d3d8.dll. Trying to install DirectX 8.0, I end up with "DirectX couldn't be installed on this computer". Any hints on this one? Sebastian --
