The stats function `plot.ecdf`

is fine for vectors that are not too large. However for n ~ 1e7 we would observe a dramatic performance breakdown (possibly in combination with the use of `do.call`

).

`PlotECDF`

is designed as alternative for quicker plotting the ecdf for larger vectors. If `breaks`

are provided as argument, a histogram with that number of breaks will be calculated and the ecdf will use those frequencies instead of respecting every single point.

Note that a plot will rarely need more than ~1'000 points on x to have a sufficient resolution on usual terms. `PlotFdist`

will also use this number of breaks by default.
