Richard,
There are usually several methods available - depending on the class of
the object you apply 'hist' on.
In this case two are 'non-visible'
######
> methods(hist)
[1] hist.Date* hist.default hist.POSIXt*
Non-visible functions are asterisked
######
Probably you are interested in hist.default
######
> hist.default
function (x, breaks = "Sturges", freq = NULL, probability = !freq,
include.lowest = TRUE, right = TRUE, density = NULL, angle = 45,
col = NULL, border = NULL, main = paste
...
snip
...
}
else r
}
<environment: namespace:graphics>
