rawXLim
returns the current plot limits, on a numeric, linear scale.
This is as simple as:
playDo(playState, space=space, list(
x=convertX(unit(0:1, "npc"), "native", valueOnly=TRUE),
y=convertY(unit(0:1, "npc"), "native", valueOnly=TRUE)))
except that the default space="plot"
will always return a value: if
it is a Lattice plot with multiple panels, one will be chosen arbitrarily.
The assignment form converts a numeric range, in the raw native plot coordinates, to values suitable for
the plot xlim
argument: it may convert back from log-transformed scales, and convert to factor levels if necessary.
It then updates the current plot call with the new value.
