plot.lengths: Plot Stratum Lengths

Description

The function makes a graphical representation of the stratum lengths.

Usage

"plot"(x, ..., log = FALSE, zeros.rm = TRUE)

Arguments

x
an object of the class lengths, typically with the output of the function getlen.
...
other arguments to pass to the function boxplot.
log
a logical value. If TRUE, the logarithm of the stratum lengths will be plotted. It is FALSE by default.
zeros.rm
a logical value. If FALSE, the image will be drawn by including zero values. It is TRUE by default.

Value

boxplot.lengths, the same image is produced. The function returns a list with the following components:
stats
a matrix containing the values used to plot the box-and-whisker plots.
n
a vector with the number of observations for each category.
conf
a matrix containing further values to draw the lower and upper extremes of the notch.
out
a vectors with the values of the outlier points.
group
a vector whose elements indicate to which category the outlier belongs.
names
a character vector with the names of each category.

Details

The box-and-whisker plots give some information about the distribution of the stratum lengths for the observed categories along a given direction.
