Stacked histogram
histStack(x, breaks, midsFun=paste, ...)
x |
A list of numeric vectors. |
breaks |
Histogram breaks, as in
hist |
midsFun |
Function, can be used to control the formatting and number of the bar labels on the x-axis. See example. |
... |
Further arguments that get passed to
barplot |
The function calls hist
for each element of x and plots the frequencies
as a stacked barplot using
barplot with beside=FALSE.
The function is called for its side effect, producing a barplot
on the active graphics device. It returns the result of the call to
barplot.
