[Env: R 2.11.1, Win Xp, using Eclipse/StatET]
In a package I'm working on, I want to create as.matrix() and as.array()
methods for a particular kind of
object (log odds ratios). These are returned in a loddsratio object as
the $coefficients component,
a vector, but really reflect an underlying (R-1)x(C-1)xstrata array,
whose attributes are contained in other
components.
I define coef, dim and dimnames methods, and then want an as.array method,
## dim methods
dimnames.loddsratio <- function(object, ...) object$dimnames
dim.loddsratio <- function(object, ...) object$dim
coef.loddsratio <- function(object, log = object$log, ...)
if(log) object$coefficients else exp(object$coefficients)
as.array.loddsratio <- function (x, log=x$log, ...)
drop(array(coef(x, log = log), dim = dim(x), dimnames=dimnames(x)))
I believe everything is declared properly in the NAMESPACE file, e.g.,
...
S3method(dim, loddsratio)
S3method(dimnames, loddsratio)
S3method(print, loddsratio)
S3method(vcov, loddsratio)
S3method(as.matrix, loddsratio)
S3method(as.array, loddsratio)
All my tests work correctly when run in the R console, but R CMD check
gives me a perplexing warning:
* checking whether package 'vcdExtra' can be installed ... WARNING
Found the following significant warnings:
Warning: found an S4 version of 'as.array' so it has not been
imported correctly
See 'C:/eclipse/vcdExtra.Rcheck/00install.out' for details.
It's just a warning, so maybe I can ignore it, but I can't figure out
where this might have come from.
Has anyone seen this before? Where might an S4 version of as.array be
found?
