Empirical Cumulative Density Function
stat_ecdf(mapping = NULL, data = NULL, geom = "step", position = "identity", n = NULL, ...)
n |
if NULL, do not interpolate. If not NULL, this is the number of points to interpolate with. |
mapping |
The aesthetic mapping, usually constructed
with |
data |
A layer specific dataset - only needed if you want to override the plot defaults. |
geom |
The geometric object to use display the data |
position |
The position adjustment to use for overlappling points on this layer |
... |
other arguments passed on to
|
a data.frame with additional columns:
x |
x in data |
y |
cumulative density corresponding x |
