This is a new check in R-devel. The NEWS say:
> R CMD check etc now warn when a package exports non-existing S4 classes or
> methods, also in case of no "methods" presence
In your case, the NAMESPACE contains
> exportClasses(classify)
> exportClasses(gonad_mature)
> exportClasses(morphMat)
but your package does not define these S4 classes.
You seem to instruct roxygen2 to create these invalid directives using
@exportClass tags manually instead of just @export. Simply remove these
wrong @exportClass tags from your source files and regenerate your
NAMESPACE.
