In robustlmm: Robust Linear Mixed Effects Models

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'
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_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.

Examples

plot(huberPsiRcpp)
plot(huberPsiRcpp, which=c("psi", "Dpsi", "wgt"),
     main="short", leg = "topleft")

plot(smoothPsi)
## Plotting aspect ratio = 1:1 :
plot(smoothPsi, asp=1, main="short",
     which = c("psi", "Dpsi", "wgt", "Dwgt"))
