Build Graphs for Landscape Genetics Analysis.

Description

Build graphs for landscape genetics analysis. This set of functions can be used to import and convert spatial and genetic data initially in different formats, import landscape graphs created with 'GRAPHAB' software (Foltete et al., 2012) <doi:10.1016/j.envsoft.2012.07.002>, make diagnosis plots of isolation by distance relationships in order to choose how to build genetic graphs, create graphs with a large range of pruning methods, weight their links with several genetic distances, plot and analyse graphs, compare them with other graphs. It uses functions from other packages such as 'adegenet' (Jombart, 2008) <doi:10.1093/bioinformatics/btn129> and 'igraph' (Csardi et Nepusz, 2006) <https://igraph.org/>. It also implements methods commonly used in landscape genetics to create graphs, described by Dyer et Nason (2004) <doi:10.1111/j.1365-294X.2004.02177.x> and Greenbaum et Fefferman (2017) <doi:10.1111/mec.14059>, and to analyse distance data (van Strien et al., 2015) <doi:10.1038/hdy.2014.62>.

graph4lg

Overview

The goal of graph4lg is to make easier the construction and analysis of genetic and landscape graphs in landscape genetics studies (hence the name graph4lg). The package allows to weight the links and to prune the graphs by several ways. To our knowledge, it is the first software which enables to create genetic graphs with such a large variety of parameters. Besides, it allows to carry out preliminary analyses of the spatial pattern of genetic differentiation in order to choose the best genetic distance and pruning method in every context. Lastly, it makes possible the comparison of two spatial graphs sharing the same nodes.

Installation

You can install the released version of graph4lg from CRAN with:

install.packages("graph4lg")

Example

The package includes a tutorial with examples showing why and how to use each of the included functions. The package also includes data sets in order to test the functions.

More complete tutorials in English or French language are available for more details.
