Frequency plot of univariate data.
|A vector of data from a univariate population.|
|Optional input. If |
xn is given, the frequncies are calculated for the intervals
[ xn xn ] , [xn xn ] , etc.
This function displays a plot of the number of data points in a given interval
against the intervals. If the second input is not specified, the intervals
are between eleven equally spaced points between the minimum and maximum
values of the input. Otherwise the second input is used for computing
the frequency of occurrences of data points.
