msir (version 1.3.3)

plot.msir: Plot method for 'msir' objects.

Description

Plots directions and other information from MSIR estimation.

Usage

# S3 method for msir
plot(x, which, 
     type = c("pairs", "2Dplot", "spinplot", "evalues", "coefficients"), 
     span = NULL, std = TRUE, ylab, xlab, restore.par = TRUE, ...)

Arguments

x

a 'msir' object.

which

a vector of value(s) giving the directions for which the plot should be drawn.

type

the type of plot to be drawn.

span

the span of smoother (only for type = "pairs" | "2Dplot").

std

if TRUE coefficients are standardized (only for type = "coefficients").

ylab

a character string for the y-axis label.

xlab

a character string for the x-axis label.

restore.par

if TRUE the graphical parameters (see par) changed are restored to the previous state. If you want to manipulate the resulting plot you should set restore.par = FALSE.

...

additional arguments.
