plotvgam.control

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", ...)

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.
`...`	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.
