F_2_panel.smoothScatter: Lattice panel function analogous to smoothScatter

Description

This function allows the user to place smoothScatter plots in lattice graphics.

Usage

panel.smoothScatter(x, y = NULL,
                    nbin = 64, cuts = 255,
                    bandwidth,
                    colramp,
                    nrpoints = 100,
                    transformation = function(x) x^0.25,
                    pch = ".",
                    cex = 1, col="black",
                    range.x,
                    ...,
                    raster = FALSE,
                    subscripts,
                    identifier = "smoothScatter")

Value

The function is called for its side effects, namely the production of the appropriate plots on a graphics device.

Details

This replicates the display part of the smoothScatter function by replacing standard graphics calls by grid-compatible ones.

Examples

ddf <- as.data.frame(matrix(rnorm(40000), ncol = 4) + 3 * rnorm(10000))
ddf[, c(2,4)] <- (-ddf[, c(2,4)])
xyplot(V1 ~ V2 + V3, ddf, outer = TRUE,
       panel = panel.smoothScatter, aspect = "iso")
splom(ddf, panel = panel.smoothScatter, nbin = 64, raster = TRUE)
