Thank you Gabor, that showed me I really needed to be more creative with
the 'breaks' argument. So what I needed was (with mychron as above):
breaks <- seq(min(mychron, na.rm = TRUE),
ceiling(max(mychron, na.rm = TRUE)), by = 1/2)
cut(unclass(mychron), unclass(breaks),
include.lowest = TRUE, labels = FALSE)
in order to cut the chron object into 1/2 day units.
Thanks so much,
