graph.freq: Frequency table histogram

Description

In many situations it has intervals of class defined with its respective frequencies. By means of this function, the picture of frequency is obtained and it is possible to superpose the normal distribution, polygon of frequency, Ojiva and to construct the table of complete frequency.

Usage

graph.freq(breaks, counts, ...)

Arguments

breaks

Class interval

counts

frequency

...

parameters hist()

Value

• breaks
  Numeric
• counts
  Numeric
