What you are saying is that an undocumented default does not apply to
your usage. So all you need to do, surely, is to set the argument
yourself?
Your 'correction' makes e.g. kernel("daniell") invalid.
I"ve applied a change in R-devel that means 'm' will not need to be
supplied if 'coef' is numeric.

Hi,
There is a small bug in the kernel() function. Everything is fine when
we use the format:
kernel("name",m,r)
but if we want the first argument to be a vector, which is useful is we
are interested in using a method not implemented in kernel(), the
default value of m is wrong. For example, if we do:
s <- rep(1/11,6)
k <- kernel(s)
we get the error message
Error in kernel(s) : 'coef' does not have the correct length
The problem is that the default value, which is not indicated in the
help file, violate the condition that length(coef) must be equal to
(m+1). Therefore, the first line of the function, which is:
function (coef, m = length(coef) + 1, r, name = "unknown")
{
should be changed to
function (coef, m = length(coef) - 1, r, name = "unknown")
{
