Usage

gen.downset(z, Q = 1)

Arguments

z	an incidence matrix.
Q	a vector (boolean, numeric that indexes the profiles, or character as the profiles names) to select an downset.

Value

A boolean vector.

Examples

lv <- c(2, 3, 2)
prof <- var2prof(varlen = lv)

z <- getzeta(prof)
down <- c("111", "211", "112", "212")
gen <- gen.downset(z, down)

plot(z, lwd = 1 + (rownames(prof$profiles)%in%down), col = 1 + gen, sub = "bold = the downset, red = the subset that generates the downset")
