plotvgam.control: Control Function for plotvgam()

In VGAM: Vector Generalized Linear and Additive Models

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()$lty, slty = "dashed",
    pcex = par()$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, noxmean = FALSE,
    shade = FALSE, shcol = "gray80", main = "", ...)

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 then the plot will be added to an existing plot, otherwise a new plot will be made.
one.at.a.time	Logical. If TRUE then 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.
noxmean	Logical. If TRUE then the point at the mean of x, which is added when standard errors are specified and it thinks the function is linear, is not added. One might use this argument if ylab is specified.
shade, shcol	shade is logical; if TRUE then the pointwise SE band is shaded gray by default. The colour can be adjusted by setting shcol. These arguments are ignored unless se = TRUE and overlay = FALSE; If shade = TRUE then scol is ignored.
main	Character vector, recycled to the number needed.
...	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.
