zoom: Zoom

Description

Change text size in a lattice plot.

Usage

zoom(x, ...)
# S3 method for trellis
zoom(x, size = 1, main = 1.2 * size, lab = size,
  axis = size, strip = size, sub = 0.9 * size, legend = 0.9 * size,
  splom = 0.9 * size, ...)

Value

The same lattice object, but with altered text size.

Arguments

x: a lattice plot of class "trellis".
...: further arguments, currently ignored.
size: text size multiplier.
main: size of main title (default is 1.2 * size).
lab: size of axis labels (default is size).
axis: size of tick labels (default is size).
strip: size of strip labels (default is size).
sub: size of subtitle (default is 0.9 * size).
legend: size of legend labels (default is 0.9 * size).
splom: size of scatterplot matrix diagonal labels (default is 0.9 * size).

Details

Pass NULL for any argument to avoid changing the size of that text component.

The legend component of a lattice plot can be somewhat fickle, as the object structure varies between plots. One solution is to pass legend = NULL and tweak the legend before or after calling the zoom function.

Examples

Run this code

library(lattice)

xyplot(1~1)
zoom(xyplot(1~1))
zoom(xyplot(1~1), size=1.2)
zoom(xyplot(1~1), axis=0.8)
zoom(xyplot(1~1), axis=NULL)

if (FALSE) {
taf.png("myplot")
plot(1)
dev.off()

taf.png("mytrellis")
xyplot(1~1)
dev.off()

taf.png("mytrellis_zoom")
zoom(xyplot(1~1))
dev.off()
}
