panel.plotFun1: Panel function for plotting functions

Description

Panel function for plotting functions

Usage

panel.plotFun1(..f.., ..., x, y, type = "l",
  col = trellis.par.get("superpose.line")$col, npts = NULL, zlab = NULL,
  filled = TRUE, levels = NULL, nlevels = 10, surface = FALSE,
  alpha = NULL)

Arguments

..f..

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

...

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

x,y

ignored, but there for compatibility with other lattice panel functions

type

type of plot ("l" by default)

col

a vector of colors

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

alpha

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.plotFun1( sin, col='red' ) )
xyplot( y ~ x | rbinom(30,1,.5), data=d )
ladd(panel.plotFun1( sin, col='red', lty=2 ) )    # plots sin(x) in each panel
