I might be tempted to take a more generic approach, where one can
provide an argument to the function to indicate that I want the 'top x'
maximum values and to give the user the option of returning the indices
or the values themselves.
Perhaps:
which.max2 <- function(x, top = 1, values = FALSE)
{
if (values)
rev(sort(x))[1:top]
else
order(x, decreasing = TRUE)[1:top]
}
Very cool too! .. Thanks Marc. Again, I did not get this from the
order documentation (ie that it manipulate index values rather than
the values themselves). Great to see examples.
Best,
