glPlot | R Documentation |
genlight object can be plotted using the function
glPlot
, which is also used as the dedicated plot
method. These functions relie on image
to represent SNPs
data. More specifically, colors are used to represent the number of
second allele for each locus and individual.
glPlot(x, col=NULL, legend=TRUE, posi="bottomleft", bg=rgb(1,1,1,.5),...) ## S4 method for signature 'genlight' plot(x, y=NULL, col=NULL, legend=TRUE, posi="bottomleft", bg=rgb(1,1,1,.5),...)
x |
a genlight object. |
col |
an optional color vector; the first value corresponds to 0
alleles, the last value corresponds to the ploidy level of the
data. Therefore, the vector should have a length of ( |
legend |
a logical indicating whether a legend should be added to the plot. |
posi |
a character string indicating where the legend should be positioned. Can be any concatenation of "bottom"/"top" and "left"/"right". |
bg |
a color used as a background for the legend; by default,
transparent white is used; this may not be supported on some
devices, and therefore background should be specified
