Description

This data set contains informations about Buech basin characteristics.

Usage

data(buech)

Format

buech is a list with the following components :

tab1
: a data frame with 10 environmental variables collected on 31 sites in Juin (1984)
tab2
: a data frame with 10 environmental variables collected on 31 sites in September (1984)
xy
: a data frame with the coordinates of the sites
neig
: an object of class neig
contour
