plot.between.Rd

Outputs and graphical representations of the results of a between-class analysis.

Usage

# S3 method for class 'between'
plot(x, xax = 1, yax = 2, ...) 
# S3 method for class 'between'
print(x, ...)
# S3 method for class 'betcoi'
plot(x, xax = 1, yax = 2, ...)
# S3 method for class 'betcoi'
print(x, ...)
# S3 method for class 'between'
summary(object, ...)

Arguments

x,object

an object of class between or betcoi

xax, yax

the column index of the x-axis and the y-axis

...

further arguments passed to or from other methods
