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]]
image(list(x = 0:9, y = 0:9, z = z))
}
par(opar) #restore device parameters
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$y
so that it could be used in the sense of:
my.list[[p$slice]][round(p$x), round(p$y)]
many thanks
Cheers
christoph
