Appropriate method for sharing data across functions
...i.e., cannot be interpreted but must be built first.
JN
Example using <<-
rm(list=ls())
optstart<-function(npar){ # create structure for optimization computations
# npar is number of parameters ?? test??
OPCON<<-list(MAXIMIZE=TRUE, PARSCALE=rep(1,npar), FNSCALE=1,
KFN=0, KGR=0, KHESS=0)
# may be other stuff
ls(OPCON)
}
add1<-function(){

test<-OPCON$KFN

help on spatial data
...xample, the fisrt area (area1) have a random distribution, and my
hypothesis is false, in second area (area2) I have an aggregated distribution
and my hypothesis is true.
I real data I can have several levels of aggregation, I need testing these
difference of aggregations.
I try to use the Kfn from spatial package, but I dont succeed.
R have any package to make this analyse?
What I need to read for this?
Thanks for all

Is it possible to do Ripley's K and L functions analysis with R?
Dear friends,
I am studying the spatial distribution of trees in
a tropical swamp forest in Brazil, and the spatial
association between the trees and other forest and non
forest elements. These are point pattern analysis of
mapped data, preferentially done with the L function
of Ripley.
I have recently discovererd the R-project and would
like to know whether it is possible to do these

avoiding for loops
I have data that looks like this:
> df1
group id
1 red A
2 red B
3 red C
4 blue D
5 blue E
6 blue F
I want a list of the groups containing vectors with the ids. I am
avoiding subset(), as it is
only recommended for interactive use. Here's what I have so far:
df1 <- data.frame(group=c("red", "red", "red", "blue",
