plot (plot.default) is "old-style" graphics and dates before grid.
Note that your program would run without error when you remove
the library(grid).
Use print(xyplot(..)) instead, or use par(...) to generate the
layout for your standard plots.

Alternatively, you can
- use grid.points or a similar grid function to create the plot, as
described in Paul Murrell's tutorial,
http://www.stat.auckland.ac.nz/~paul/grid/doc/plotexample.pdf
- use ggplot2 instead of plot
- use gridBase to mix base graphics and grid graphics
- use split.screen in combination with base graphics

[R] Simple Plot with Grid's Viewport
Dear all,
I have the following code that try to plot
simple sinus curve into 2x2 grid in 1 page.
But this code of mine create 4 plots in 1 page
each. What's wrong with my approach?
__BEGIN__
library(lattice)
library(grid)
test.plot <- function(x,y) {
pushViewport(viewport(layout.pos.col=x, layout.pos.row=y))
pushViewport(viewport(width=0.6, height=0.6));
plot(sin,-pi,2*pi, main= paste(c(i,j),collapse="-") )
}
plotfn <- ("~/Desktop/mygrid.pdf")
pdf(plotfn)
id = 0;
for (i in 1:2) {
for (j in 1:2) {
id = id+1;
cat(i, "-", j, "\n", sep="")
test.plot(i,j);
}
}
dev.off()
__END__
