R help - Jan 2008 - Adding a table to a lattice plot

Hi,

   Is there an analog function of textplot in the
lattice package? I need to add a data frame to a
lattice plot. I work in a Windows environment and I am
using R v 2.6.1

Thank you,

Judith

There's nothing built-in, but if you are happy with fixed width text,
a simple wrapper to capture.output() should be good enough. Here's one
approach:

panel.textplot <-
    function(object, ...,
             gp = gpar(fontfamily = "mono"))
{
    require(grid)
    foo <- capture.output(object)
    grid.text(paste(foo, collapse = "\n"), ..., gp = gp)
}


xyplot(1 ~ 1,
       panel = function(...) {
           panel.xyplot(...)
           panel.textplot(head(iris))
       })

You could use other arguments to grid.text() in the call to
panel.textplot(), giving a fair amount of control over placement etc.
