plot_freq: Histogram and frequency polygon

In rodianf/histogramR: Frequency distribution tables, histograms and frequency polygons

Description

Creates an histogram and frequency polygon or a cummulative frequency polygon.

Usage

plot_freq(x, nclass = "Sturges", density = FALSE, cfp = FALSE)

Arguments

x	a numerical vector.
nclass	a character string. Method for calculation of the number of classes from a numerical random variable.
density	logical; if TRUE, the histogram graphic is a representation of frequencies, the counts component of the result; if FALSE, probability densities, component density, are plotted (so that the histogram has a total area of one).
cfp	logical, indicating if the plot is an histogram and frequency polygon or a cummulative frequency polygon.

Value

A ggplot2 object.

Examples

data <- rnorm(100)
plot_freq(data)
plot_freq(data, nclass = "FD", cfp = TRUE)

# Change graphical parameters
