similar to: integrate() (PR#1755)

Dear @ll. I have to calculate numerical integrals for triangular and trapezoidal figures. I know you can calculate the exactly, but I want to do it this way to learn how to proceed with more complicated shapes. The code I'm using is the following: integrand<-function(x) { print(x) if(x<fx[1]) return(0) if(x>=fx[1] && x<fx[2]) return((x-fx[1])/(fx[2]-fx[1]))

Hi, I've searched the archives for a discussion on the use of R for developing "small world" or "scale-free" network models but have been unable to dig anything up. Is anyone working on these types of models using R, and if so, have you found this language amenable to their development? thanks, matt farnsworth

Hi, I install rJava in linux. The installation, from source, is ok. But I have this error on load package. > library(rJava) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library '/usr/local/lib/R/site-library/rJava/libs/rJava.so': libjvm.so: cannot open shared object file: No such file or directory Error: .onLoad failed in

Greetings list, I'm currently in the process of migrating some Matlab code to R. It's going well, but I'm running into trouble with plotting. There are a few questions I have. 1) Is there any way to do a 3D line plot in R? This would be what the Matlab function plot3 does. 2) I would like to create 3 separate plots. With Matlab, this is done by doing ... figure; plot...
