[R-pkg-devel] Warning: S4 exports specified in 'NAMESPACE' but not defined in package
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("bujar")
exportMethods("show")
but the package neither defines an S4 class "bujar" nor methods for the S4 generic "show". You should remove these two lines from your NAMESPACE. Best regards, Sebastian Meyer Am 01.06.20 um 18:34 schrieb Wang, Zhu:
Dear All, I received warnings regarding a package: https://cran.r-project.org/web/checks/check_results_bujar.html The warning still occurred after I changed export(bujar, gcv.enet) to export(bujar) in NAMESPACE. The function bujar was defined in the package, so I probably missed something in Sec 1.5.6 in Writing R Extensions. Could somebody kindly advise how to address the warning?
