Hello!
Suppose I have three charts like below. The top chart is a general
overview and the bottom charts are related so some point of this chart.
To make clear this relationship I want to draw a line between (4,0.9) in
the top chart and (10,1) in the bottom-left one.
Currently I add it manually using Inkscape on the resulting pdf file.
Is it possible to add it inside R? Should I switch to other charting
packages?
You'll have your work cut out using traditional graphics, but this is
doable in grid-based graphics. For example, ...
library(grid)
library(lattice)
set.seed(123)
print(xyplot(runif(10)~1:10, type="b"),
position=c(0, .5, 1, 1),
prefix="top",
more=TRUE)
print(xyplot(runif(20)~1:20, type="l"),
position=c(0, 0, .5, .5),
prefix="left",
more=TRUE)
print(xyplot(runif(20)~1:20, type="l"),
position=c(.5, 0, 1, .5),
prefix="right")
trellis.focus("panel", 1, 1, prefix="top")
grid.move.to(unit(4, "native"), unit(.9, "native"))
trellis.unfocus()
trellis.focus("panel", 1, 1, prefix="left", clip.off=TRUE)
grid.line.to(unit(10, "native"), unit(1, "native"))
trellis.unfocus()

Thanks for the advice!
