The function adds points in multiple cells by first splitting data into several parts in which
each part corresponds to one factor (sector index) and then adding points in each cell by calling circos.points.
Length of pch, col and cex can be one, length of levels of the factors or length of
factors.
This function can be replaced by a for loop containing circos.points.
circos.initialize(letters[1:8], xlim = c(0, 1))
df = data.frame(sectors = sample(letters[1:8], 100, replace = TRUE),
x = runif(100), y = runif(100))
circos.track(ylim = c(0, 1))
circos.trackPoints(df$sectors, x = df$x, y = df$y, pch = 16, col = as.numeric(factor(df$fa)))
