Hello
I have a data set with 9700 records and 7 parameters.
The data were collected for a survey of forest communities. Sample plots
(1009) and species (139) are included in this data set. I I am about to embark on the writing of a program for R and I wanted to
know a good reference book that would be useful. There has been some
talk about S programming the Springer publication ISBN 03Hi list
I 'm looking for statisitic measurements describing the pattern of points
within a given polygon. Is there a function calculating the Index of

Hi again
Sorry in looking again at sammon and isoMDS I see that they seem to do
exactly what I want except that they are non-metric which means as I
understand it that they relate the rank ordDear R list
Would anyone be able to tell me whether it is possible to do "enhanced
multidimensional scaling " (enhanced MDS) in R? In other words something that
goes beyond "cmdscale " by iterativel
Dear useRs
a new package for tree-structured regression is available on CRAN.
This package implements a unified framework for recursive partitioning
which embeds tree-structured regression models Did some search but couldn 't find useful result.
I am trying to read a n*m dimension data with read.table what i need is a numeric array
is there any efficient way to allow me get this array direDear useRs
is there any nonparametric test for the analysis of variance in a design
with two within-factors (repeated measures on both factors)? Friedman is not
appropriate here therefore I am gratefHi
Can you tell me if there are an R package or code for STAR model estimation and test misspecification. If no how i could do this.
Thanks in advance
