plot.lengths: Plot Stratum Lengths

In spMC: Continuous-Lag Spatial Markov Chains

Plot Stratum Lengths

Description

The function makes a graphical representation of the stratum lengths.

Usage

## S3 method for class 'lengths'
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.

Details

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

Value

An image is produced on the current graphics device; by the use of 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.

Examples

data(ACM)
direction <- c(0,0,1)
     
# Compute the appertaining directional line for each location
loc.id <- which_lines(ACM[, 1:3], direction)
     
# Estimate stratum lengths
gl <- getlen(ACM$MAT3, ACM[, 1:3], loc.id, direction)

# Plot the object gl

plot(gl)
