The function produces the plot of the table()
function with colour densities
corresponding to the respective frequencies of appearance. If the value appears more
often than the other (e.g. 0.5 vs 0.15), then it will be darker. By default, the
frequency of 0 corresponds to the white colour, the frequency of 1 corresponds to the
black. The colours can be changed by defining a different palette via the
palette()
function. In that case only two first colours are used, where the
colour intensity changes from the first one to the second one. The function also
adds the number of dots (points) proportional to the number of values in each
category to simplify the reading of plots.
