[R] Hmisc::rcorr inconsistency?

[Keith.Jewell at campdenbri.co.uk]

(Copied to maintainer)

I'm not going to say there's an error in such an established and respected package but I think there's an inconsistency between the help text and the example:

> ?rcorr
   <snip>
Value
   <snip>
The diagonals of n are the number of non-NAs for the single variable corresponding to that row and column.

> example(rcorr)
   <snip>
rcorr> z <- c(1,   2, 3, 4, NA)  # number of non-NAs for z = 4
   <snip>
n
  x y z v
x 5 5 4 5
y 5 5 4 5
z 4 4 5 4  # diagonal for z = 5
v 5 5 4 5

Is this an error in the documentation or the code?
Or am I misunderstanding something?
