Plot an Object of the "Psi Function" Class

Description

The plot method objects of class PsiFunction simply visualizes the \rho(), \psi(), and weight functions and their derivatives.

Usage

## S4 method for signature 'Rcpp_SmoothPsi'
plot(x, y,
     which = c("rho", "psi", "Dpsi", "wgt", "Dwgt"),
     main = "full", 
     col = c("black", "red3", "blue3", "dark green", "light green"),
     leg.loc = "right", ...)
## S4 method for signature 'Rcpp_HuberPsi'
plot(x, y,
     which = c("rho", "psi", "Dpsi", "wgt", "Dwgt"),
     main = "full", 
     col = c("black", "red3", "blue3", "dark green", "light green"),
     leg.loc = "right", ...)
## S4 method for signature 'Rcpp_PsiFunction'

     main = "full", 
     col = c("black", "red3", "blue3", "dark green", "light green"),
     leg.loc = "right", ...)
## S4 method for signature 'Rcpp_PsiFunctionToPropIIPsiFunctionWrapper'
plot(x, y,
     which = c("rho", "psi", "Dpsi", "wgt", "Dwgt"),
     main = "full", 
     col = c("black", "red3", "blue3", "dark green", "light green"),
     leg.loc = "right", ...)

Arguments

x

instance of class PsiFunction to be plotted

y

(optional) vector of abscissa values (to plot object at).

which

character vector of slots to be included in plot; by default, all of the slots are included

main

string or logical indicating the kind of plot title; either "full", "short" or FALSE which chooses a full, a short or no main title at all.

col

colors to be used for the different slots

leg.loc

legend placement, see also x argument of legend

...

passed to matplot

Note

If you want to specify your own title, use main=FALSE, and a subsequent title(...) call.
