Dear list,
Checks of the package BaseSet I maintain are failing on r-devel with:
Error in UseMethod("tidy") : no applicable method for 'tidy' applied to
an object of class "GeneSet" Calls: tidy Execution halted
Surprisingly, similar code on tests pass without errors.
This GeneSet is a S4 class exported by GSEABase and has been exported for
several years [1]. tidy is a S3 method defined on the package.
As this package is a suggested package, following WRE recommendations [2] I
tried to register the method conditionally under requireNamespace:
if (requireNamespace("GSEABase", quietly = TRUE)) {
importClassesFrom(GSEABase, GeneSetCollection)
S3method(tidy, GeneSetCollection)
importClassesFrom(GSEABase, GeneSet)
S3method(tidy, GeneSet)
importClassesFrom(GSEABase, CollectionType)
S3method(tidy, CollectionType)
}
However, the new NAMESPACE doesn't pass checks:
* checking package dependencies ... ERROR
Namespace dependency missing from DESCRIPTION Imports/Depends entries:
‘GSEABase’
There have been some threads on r-devel about registering dependencies to
classes defined in other packages [3]. I also saw some packages that
register the S3 method via .onLoad [4]. In this package I defined several
S3 methods for an S4 class. Should I define S4 methods for S4 classes not
defined in my package?
I would appreciate some advice on how to proceed,
Lluís
