n.markers
A vector containing number of variables/markers in each group/chromosome. For example, the CviCol dataset that is provided in the package contains 5 chromosomes/ groups which the total number of markers is $p = 90$, where the first 24 markers belong into chromosome 1, the next 14 markers into chromosome 2, ..., and chromosome 5 contains 19 markers. Thus, n.mrkr = c(24,14,17,16,19). If n.mrkr = NULL
, in the graph visualization all markers are represented same colour.
