If you want to use the 'methods' package, you could do something like:
replace <- function (p1, p2, ...)
{
stop(gettextf("cannot 'replace' with arguments of class %s and %s",
sQuote(class(p1)[1L]), sQuote(class(p2)[1L])))
}
methods::setGeneric("replace")
methods::setMethod("replac
Dear List-members,
I would like to experiment with dispatching on 2 arguments and have a
few questions.
p1 = data.frame(x=1:3, coeff=1)
class(p1) = c("pm", class(p1));
I want to replace variables in a polynomial with either:
another polynomial, or another variable (character) or with a spec

In general, the search for symbols for a function Z in a package Y will span
only those namespaces that the package Y specifies. The search for symbols in a
function whose parent environment is the global environment will start there,
thereby opening the door to find masking versions of function
I have two functions which appear to differ only in their environments.
They look like:

Dear R-experts,
Here is a toy example. How can I get the bootstrap confidence

Many thanks for your help
