## Genetics-Ecology-Environment Triple

### Description

This data set contains environmental and genetics informations about 16 Euphydryas editha butterfly colonies studied in California and Oregon.

### Usage

    data(butterfly)

### Format

`butterfly` is a list with the following components:

xy

  a data frame with the two coordinates of the 16 Euphydryas editha butterfly colonies

envir

  a environmental data frame of 16 sites - 4 variables

genet

  a genetics data frame of 16 sites - 6 allele frequencies

contour

  a data frame for background map (California map)

Spatial

  an object of the class `SpatialPolygons` of `sp`, containing the map
