print.Penrose.dist: Prints Penrose's distance matrix

Description

Prints the results produced by Penrose.dist, the Penrose's distance calculator.

Usage

# S3 method for Penrose.dist
print(x, long = FALSE, ...)

Value

Displays Penrose's distances between m multivariate populations or samples. The argument x, invisibly, as for all print methods, is a list of class "Penrose.dist". This print method provides two sorts of output depending on whether the long argument is TRUE or FALSE (the default). The "short" output displays:

A heading describing the function.
The data frame analyzed.
The variables involved in the calculation of distances.
The factor defining the populations or samples and their levels.
The Penrose distance matrix (lower triangular form).

In addition to the above information, the "long" output lists:

The population or sample sizes.
The mean vector for each population / sample.
The covariance matrix for each population / sample
The pooled covariance matrix.

Arguments

x: an object of class Penrose.dist
long: a logical variable indicating whether a long output is desired (TRUE) or not (FALSE, the default). In addition to Penrose's distances, the long output displays the covariance matrix for each group with their population / sample sizes, the mean vector for each group, and the pooled covariance matrix.
...: further arguments passed to or from other methods.

Examples

Run this code

data(skulls)
res.Penrose <- Penrose.dist(x = skulls, group = Period)
# Long output
print(res.Penrose, long = TRUE)
