plotAMids: Visualises genetic distances.

Description

plotAMids is used to visualise the relationship amongst individuals and references.

Usage

plotAMids(AMids, phenoFile, columnPlot = "I", quantilePlot = TRUE, colorPlot = "BlBrewer", sepLinesPop = TRUE, plotIndNames = FALSE, legColor = TRUE, legRef = TRUE, legPheno = TRUE, legAxisPop = TRUE, legData = FALSE, bmar, lmar, tmar, rmar, cexref = 0.9, cexind = 0.8)

Arguments

AMids

Dataframe of genetic distances calculated by calculateAMids or calculateAMidsArith.

phenoFile

Optional file with phenotype, color and order information for individuals and populations. An example file, called CorPheno, is contained in the 'extdata' folder with the package.

columnPlot

Takes values 'I' or 'C'. 'I' is the default option. 'I' plots the normalised euclidean distances whereas 'C' plots the crude distances.

quantilePlot

Logical. Takes values TRUE or FALSE. TRUE is the default option. If columnPlot is 'C', TRUE will plot the quantiles, FALSE will plot the raw values.

colorPlot

Colors for the AMids. Possible choices are 'RedBl', 'RedBlGr' and 'BLBrewer'. The user can also provide a vector of colors.

sepLinesPop

Logical. Takes values TRUE or FALSE. The default is TRUE. If TRUE, a line demarcating populations is plotted.

plotIndNames

Logical. Takes values TRUE or FALSE. The default is FALSE. If TRUE, the individual ids are plotted on the left axis.

legColor

Logical. Takes values TRUE or FALSE. The default is TRUE. If TRUE, the legend for the colour gradient will be plotted in the top left.

legRef

Logical. Takes values TRUE or FALSE. The default is TRUE. If TRUE, text giving names of references will be plotted along the x axis.

legPheno

Logical. Takes values TRUE or 'no. The default is TRUE. If TRUE, will plot colour blocks relating to the population, dataset and regional origin of data if sample IDs have been given these in the Corpheno file, if not present, will plot them under 'Unspecified'.

legAxisPop

Logical. Takes values TRUE or FALSE. The default is TRUE. If TRUE text will be plotted giving name and number of populations for samples used on the right y axis of the plot.

legData

Logical. Takes values TRUE or FALSE. The default is FALSE. If TRUE, the reference to the dataset used to create the reference is appended to the reference population name on the bottom x axis.

bmar

Takes numeric value. Changes the size of the bottom outer margin of the plot. The default is empty. For more see ?par()

lmar

Takes numeric value. Changes the size of the left outer margin of the plot. The default is empty. For more see ?par()

tmar

Takes numeric value. Changes the size of the top outer margin of the plot. The default is empty. For more see ?par()

rmar

Takes numeric value. Changes the size of the right outer margin of the plot. The default is empty. For more see ?par()

cexref

Takes numeric value. Controls text size of reference names on y axis. Default is 0.9.

cexind

Takes numeric value. Controls text size of sample names on y axis. Default is 0.8. Individual sample IDs need plotIndNames = "yes" to display, this is set to FALSE by default.
