Hello, it wanted to know how I can extract of a dates frame the values peaks according to an interval that I establish.

Hello, I've put together a macports version of llvm and llvm-gcc4, but I've run into a problem with how gcc on the mac works. llvm-gcc4 creates an executable named: /opt/local/bin/powerpc-apple-darwin8-gcc-4.0.1 Which happens to be the same executable in /usr/bin. Because I have /opt/local before /usr/bin, gcc ends up using llvm-gcc4 to build all my code. Most of the time this

Hi, i 'dont understand how to take a general formula, view this: x<-1:5 y<-c(0,1,1.7,2,2.1.4) dummy<-data.frame(x=x,y=y) formula<-"y~A*log(x)/log(2)" formu<-as.formula(formula) fm<-lm(formu,data=dummy) Error in eval(expr, envir, enclos) : Object "A" not found but A is the parameter of fitting, why is this?Thanks Ruben

Greetings, We found out today that rsync has been missing some files. Here is the senerio: We have two nfs servers in different datacenters, one being the backup to the other.

Sorry to ask this but does anyone knows a good text that helps with the basic programming side of R. I understand the statistics behind most of R but i have real difficulty with the data types and how R views them. As a part of that could you help me with another problem. I know how to read data in from a file in terms of read.table but how do i single a column out or even just download a

Hi everybody, I put some R-code to a web page for drawing fractals. See http://fractalswithr.blogspot.com/ If you have some R-code for fractal images, I'm willing to include them to the page. Has somebody tried L-systems or Markov algorithm (http:// en.wikipedia.org/wiki/Markov_algorithm) with R? Best wishes, Atte Tenkanen University of Turku, Finland
