Demerelate (version 0.8-1)

geo.dist: Calculates geographic distances.

Description

Internal function to prepare geographic distances for the combined analysis with genetic relatedness.

Usage

geo.dist(pop1, pop2, onlypairs = FALSE, value)

Arguments

pop1

Specific type of dataframe as in inputformat. Population one used for calculations. Individuals passed to rows of resulting matrix. Inputformat should be standart with x and y coordinate mode for Demerelate.

pop2

Specific type of dataframe as in inputformat. Population two used for calculations. Individuals passed to columns of resulting matrix. Inputformat should be standard with x and y coordinate mode for Demerelate.

onlypairs

If set as TRUE geographic distances is calculated only for diagonal comparisons in matrix. If set as FALSE lower triangel is calculated.

value

String defining method to calculate geographic distances. Can be set as "relative" or "decimal".

Value

• matrix.share
  Object containing geographic distances.

Details

Two different methods of distance calculations are implemented in Demerelate. If using "relative", distances will be calculated from x-y coordinates using normal pythagoratic mathematics. When working with geographic positions value needs to be set to "decimal". x and y coordinates need to be given as geographic positions in decimal degrees.
