[R] Inspecting R functions

[Fredrik Lundgren]

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>
