ladd: Add to Lattice Plots

Description

Simplified lattice plotting by adding additional elements to existing plots.

Usage

ladd(x, col=1, row=1)

Arguments

x

callable graphical element to be added to a panel in a lattice plot

col, row

column and row identifying desired panel in multi-panel plots.

Details

ladd is simply a wrapper around trellis.focus and trellis.unfocus.

Examples

ladd <- function(x,col=1,row=1) { trellis.focus('panel',col,row); x ; trellis.unfocus() }
print(xyplot(rnorm(100) ~rnorm(100)))
ladd(panel.abline(a=0,b=1))
ladd(panel.abline(h=0,col='red'))
ladd(grid.text('Hello'))
ladd(grid.text(x=.95,y=.05,'text here',just=c('right','bottom')))
print(xyplot( rnorm(100) ~ rnorm(100) | factor(rbinom(100,3,.5)), layout=c(2,2) ))
ladd( grid.text("(1,1)",gp=gpar(cex=3,alpha=.5)), 1,1)
ladd( grid.text("(2,1)",gp=gpar(cex=3,alpha=.5)), 2,1)
ladd( grid.text("(1,2)",gp=gpar(cex=3,alpha=.5)), 1,2)
ladd( grid.text("(2,2)",gp=gpar(cex=3,alpha=.5)), 2,2)
