panel.plotFun: Panel function for plotting functions

Description

Panel function for plotting functions

Usage

panel.plotFun(object, ..., npts = NULL, zlab = NULL,
    lwd = 1, col = "black", filled = TRUE, levels = NULL,
    nlevels = 10, surface = FALSE,
    colorscheme = topo.colors, type = "l",
    transparency = NULL)

Arguments

object

an object (e.g., a formula) describing a function

...

additional arguments passed on to other panel functions

npts

an integer giving the number of points (in each dimension) to sample the function

zlab

label for z axis (when in surface-plot mode)

lwd

line width for line graphs and contours

col

color for line graphs and contours

filled

fill with color between the contours (TRUE by default)

levels

levels at which to draw contours

nlevels

number of contours to draw (if levels not specified)

surface

a logical indicating whether to draw a surface plot rather than a contour plot

colorscheme

a function (topo.colors by default) for choosing colors for fill

type

type of plot ("l" by default)

transparency

number from 0 (transparent) to 1 (opaque) for the fill colors

Examples

x <- runif(30,0,2*pi)
d <- data.frame( x = x,  y = sin(x) + rnorm(30,sd=.2) )
xyplot( y ~ x, data=d )
ladd(panel.plotFun( sin(x) ~ x ) )
