Hi Michael,
Many thanks for helping.
As your suggestion, i added "importMethodsFrom(AnnotationDbi, as.list)" in
NAMESPACE and added "Depends: AnnotationDbi" in DESCRIPTION.
Finally, it worked correctly.

This is because your package NAMESPACE does not import the S4 generic for
as.list. Since you're relying on S4 methods for as.list from AnnotationDbi, add
importMethodsFrom(AnnotationDbi, as.list).

Dear guys,
I want to convert S4 object into list.
When I perform the following on RStudio, the expected result can be obtained.
x <- as.list(hgu133aENTREZID)
#hgu133aENTREZID is a S4 object, after the above command, x can be converted
into list.
When I try to build above command into an R package and check it, there is an
error during the checking phase.
Error in as.list.default((hgu133aENTREZID)) :
no method for coercing this S4 class to a vector
Calls: -> as.list -> as.list.default
Execution halted
Why I can not convert S4 into list during the checking package.
Any help would be appreciated.
