I'm trying to R CMD check a package, and I'm getting the 'checking S3
generic/method consistency' warning.
I have written a function 'gamma.dist' which is _not_ an S3 method,
but happens to collide with the 'gamma' function from the R::base
namespace.
Is there a way of telling CMD check that the name is intentional and
is not meant to be an S3 method?
My function is defined as follows:
gamma.dist <- function(x,alpha,beta,observed=FALSE) {
attr(x,"distributed") <- "gamma"
attr(x,"alpha") <- substitute(alpha)
attr(x,"beta") <- substitute(beta)
attr(x,"observed") <- observed
attr(x,"env") <- new.env()
class(x) <- "mcmc.object"
x
}
with corresponding man page:
\name{normal.dist}
\alias{normal.dist}
\alias{uniform.dist}
\alias{gamma.dist}
\alias{bernoulli.dist}
\alias{binomial.dist}
...
...
\usage{
normal.dist(x, mu, tau, observed = FALSE)
uniform.dist(x, lower, upper, observed = FALSE)
gamma.dist(x, alpha, beta, observed = FALSE)
bernoulli.dist(x, p, observed = FALSE)
binomial.dist(x, n, p, observed = FALSE)
}
I am reluctant to change the name of the function b/c all my
distribution methods use the same convention of 'distribution
type'.dist.
Do CRAN maintainers view this warning as a blocker for the package
(full make check output below, which includes a few additional
warnings I'm in the process of fixing)?
Thanks,
