gl.smearplot: Smear plot of SNP or presence/absence (SilicoDArT) data

In dartR: Importing and Analysing 'SNP' and 'Silicodart' Data Generated by Genome-Wide Restriction Fragment Analysis

Smear plot of SNP or presence/absence (SilicoDArT) data

Description

Each locus is color coded for scores of 0, 1, 2 and NA for SNP data and 0, 1 and NA for presence/absence (SilicoDArT) data. Individual labels can be added and individuals can be grouped by population.

Plot may become cluttered if ind_labels If there are too many individuals, it is best to use ind_labels_size = 0.

Usage

gl.smearplot(
  x,
  ind_labels = FALSE,
  group_pop = FALSE,
  ind_labels_size = 10,
  plot_colors = NULL,
  posi = "bottom",
  save2tmp = FALSE,
  verbose = NULL
)

Arguments

x	Name of the genlight object containing the SNP or presence/absence (SilicoDArT) data [required].
ind_labels	If TRUE, individuals are labelled with indNames(x) [default FALSE].
group_pop	If ind_labels is TRUE, group by population [default TRUE].
ind_labels_size	Size of the individual labels [default 10].
plot_colors	Vector with four color names for homozygotes for the reference allele, heterozygotes, homozygotes for the alternative allele and for missing values (NA), e.g. four_colours [default NULL]. Can be set to "hetonly", which defines colors to only show heterozygotes in the genlight object
posi	Position of the legend: “left”, “top”, “right”, “bottom” or 'none' [default = 'bottom'].
save2tmp	If TRUE, saves plot to the session temporary directory (tempdir) [default FALSE].
verbose	Verbosity: 0, silent or fatal errors; 1, begin and end; 2, progress log; 3, progress and results summary; 5, full report [default NULL].

Value

Returns unaltered genlight object
