Hello all:
Is it possible to generate quasi-random positive numbers, given a standard
deviation and mean? I need all positive values to have the same probability

runif(10, min = 0, max = 100)
This way I'm generating random positive numbers fro
Hello:
I have a list of data frames, built like this: the second df is a result of
a function applied to the first, and so on.

What I want to do is quite simple, but I can't find a way.
I have a data frame with several points (x and y coords). I want to add
another column with cluster membership. For example aggregate all the points
that stand within a distance of 40 from each other.
I've tried using "n
Hello:
I have some C++ code and I want to know if it is ok to load it into R using
.Call.
Also, what's the difference between using Rdefines.h or Rinternals.h

I've been reading "Writing R Extensions" but I'm a bit confused.
Thanks,

Hello all:
I'm sure this is quite simple, but I tried several options and I still can't
get I right.
I've got a data.frame and I want to delete all columns of which the sum is

Any ideas? Thanks,
