Control Function for plotvgam()

Description

Provides default values for many arguments available for plotvgam().

Usage

plotvgam.control(which.cf = NULL,
                  xlim = NULL, ylim = NULL, llty = par()$lty,
                  slty = if (is.R()) "dashed" else 3, pcex = par()$cex,
                  pch = par()$pch, pcol = par()$col,
                  lcol = par()$col, rcol = par()$col,
                  scol = par()$col, llwd = par()$lwd, slwd = par()$lwd,
                  add.arg = FALSE, one.at.a.time = FALSE,
                  .include.dots = TRUE, ...)

Arguments

which.cf Integer vector specifying which component functions are to be plotted (for each covariate). Must have values from the set {1,2,...,M}.
xlim Range for the x-axis.
ylim Range for the y-axis.
llty Line type for the fitted functions (lines). Fed into par(lty).
slty Line type for the standard error bands. Fed into par(lty).
pcex Character expansion for the points (residuals). Fed into par(cex).
pch Character used for the points (residuals). Same as par(pch).
pcol Color of the points. Fed into par(col).
lcol Color of the fitted functions (lines). Fed into par(col).
rcol Color of the rug plot. Fed into par(col).
scol Color of the standard error bands. Fed into par(col).
llwd Line width of the fitted functions (lines). Fed into par(lwd).
slwd Line width of the standard error bands. Fed into par(lwd).
add.arg Logical. If TRUE, the plot will be added to an existing plot, otherwise a new plot will be made.
one.at.a.time Logical. If TRUE, the plots are done one at a time, with the user having to hit the return key between the plots.
.include.dots Not to be used by the user.
... Other arguments that may be fed into par().

In the above, M is the number of linear/additive predictors.

Details

The most obvious features of plotvgam can be controlled by the above arguments.

Value

A list with values matching the arguments.

Note

This function enables plotvgam() to work in a similar manner to S-PLUS's plot.gam(). However, there is no interactive options yet.
