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 |
object of class psi_func to be plotted
|
y |
(optional) vector of abscissa values (to plot object at).
|
which |
character vector of slots to be included in

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

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