Hi
based on some code from Thomas Petzoldt, I have a question:
---
opar - par(mfrow = c(2,4))
slices - 8
m - matrix(runif(100),10,10)
my.list - list()
for (slice in 1:slices) {
my.list[[slice]] - m
}
for (slice in 1:slices) {
x - 1*(1:25)
y - 1*(1:25)
z - my.list[[slice]]
p - locator(1)
c(round(p$x), round(p$y))
---
how can I get the correct location in the sense of a
3d info: (a) which slice (p$slice) (b) p$x (c) p$y
Okay, purely off the top of my head here...
You can use par()$usr, par()$plt, and par()$fig to transform from
locator()'s coordinates to device
