Dear R helper,
does anyone have an idea on why R.2.4.0 draws the surface for the two
command lines below and the next time it renders the error message below
for exactly the same command lines:
norm.cop - normalCopula(0.5)
persp(norm.cop, dcopula)
Error in ceiling(length.out) : Non-numeric
As there is no function normalCopula in R 2.4.0, your example is
incomplete. Please see the footer of this message (and perhaps contact
the maintainer of the package involved).
Please don't send messages repeatedly: if you don't get an answer the
first time study the posting guide and work
