ggtortoises: Microsatellites of Galapagos tortoises populations

Description

This data set gives genetic relationships between Galapagos tortoises populations with 10 microsatellites.

Usage

data(ggtortoises)

Format

ggtortoises is a list with the following components:

area

a data frame designed to be used in the area.plot function

ico

a list of three pixmap icons representing the tortoises morphotypes

pop

a data frame containing meta informations about populations

misc

a data frame containing the coordinates of the island labels

loc

a numeric vector giving the number of alleles by marker

tab

a data frame containing the number of alleles by populations for 10 microsatellites

Spatial

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