[R-pkg-devel] S4 methods
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. Best regards, Sebastian Meyer Am 02.06.20 um 10:01 schrieb Edgar Josymar Torrej?n-Magallanes:
Dear members I just finished some minor updates to an R package (sizeMat) I've had on CRAN (haven't had to update in a month). My package passes Check on my local machine, but it just bounced back from CRAN with the message Warning: S4 exports specified in 'NAMESPACE' but not defined in package 'sizeMat' I use roxygen2 to build my package NAMESPACE and don't have any S4 exports that I'm aware of. Perhaps this might be related to changes in R version 4.0.0? How could I fix this problem? Thanks.
