panel.plotFun: Panel function for plotting functions

Description

Panel function for plotting functions

Usage

panel.plotFun(object, ..., type = "l", npts = NULL, zlab = NULL,
  filled = TRUE, levels = NULL, nlevels = 10, surface = FALSE,
  col.regions = topo.colors, alpha = NULL, discontinuity = NULL,
  discontinuities = NULL)

Arguments

object

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

...

additional arguments, typically processed by lattice panel functions such as panel.xyplot or panel.levelplot. Frequen

type

type of plot ("l" by default)

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)

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

col.regions

a vector of colors or a function (topo.colors by default) for generating such

alpha

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

discontinuity

a positive number determining how sensitive the plot is to potential discontinuity. Larger values result in less sensitivity. The default is 1. Use discontinuity = Inf to disable discontinuity detection. Discontinuity detection uses a cr

discontinuities

a vector of input values at which a function is discontinuous or NULL to use a heuristic to auto-detect.

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, col='red' ) )
xyplot( y ~ x | rbinom(30,1,.5), data=d )
ladd(panel.plotFun( sin(x) ~ x, col='red', lty=2 ) )    # plots sin(x) in each panel
