indexing within panels in xyplot
...nd different
symbols within each panel for the levels of the second factor. My problem
is selecting the subset of each combination through which the line should
be fit for subsequent plotting. This hopefully shows the idea:
---<---------------cut here---------------start-------------->---
toydf <- expand.grid(1:100, c("A", "B"),
c("pop1", "pop2", "pop3", "pop4", "pop5"))
toydf <- data.frame(facA = toydf[[3]], facB = toydf[[2]],
x = toydf[[1]], y = rnorm(1000))
xyplot(y ~ x...

reshaping result of by()
...or further analyses, I need to have the result
arranged in a new data frame, with the upper limit of the histogram's
breaks, the per bin count, and the factors identifying each record. My
problem is including the latter:
---<---------------cut here---------------start-------------->---
toydf <- expand.grid(sample(0:50, 50, TRUE), c("A", "B"),
c("pop1", "pop2", "pop3", "pop4", "pop5"))
"getFreq" <- function(x, bks)
{
fhist <- hist(x, breaks = bks, plot = FALSE,...
