[R] Count of Histogram Bins using Shingles with lattice

You can use the functions in lattice to compute the shingle and display the
results, but they do not seem to be stored:

> set.seed(42)
> vals <- runif(100)*100
> ints <- co.intervals(vals, number=5, overlap=.25)
> cts <- shingle(vals, ints)

cts contains has the original data and the range of each level. You can get
the counts in each level with 

> summary(cts)
Intervals:
          min      max count
1  0.02362834 25.54314    25
2 20.76563596 47.49997    25
3 39.84827982 66.74291    25
4 61.91566269 83.29187    25
5 77.58207495 98.88943    25

Overlap between adjacent intervals:
[1] 6 7 6 6
