Re: [R] setMethods/setGeneric problem when R CMD CHECK'ing a package
Hmm, so I moved the function call to the same file as the methods
call, and placed it above the method in the file -- but I'm getting
the same error. Is there something "odd" about as.yearmon in the zoo
package that it might not be getting defined as a generic function?
If so, how would I go about creating a generic?
setGeneric("as.yearmon") doesn't seem to cut it.
Here's the new file contents:
as.yearmon.SpatialPointsDataFrameListZoo=function(x,...)
{
newlist=mapply(zoo:::as.yearmon,x@list,MoreArgs=list(...),simplify=FALSE)
x@list=newlist
return(x)
}
setMethod("as.yearmon",
signature(x = "SpatialPointsDataFrameListZoo"),
as.yearmon.SpatialPointsDataFrameListZoo
)

setGeneric("as.yearmon") doesn't seem to cut it.
I haven't looked at the details but just commented on the obvious
glitches in your code. Now that I tested with R-2.13.1 patched, zoo
1.7-4, sp 0.9-84, it just works for me:
setClass("SpatialPointsDataFrameList",representation(list="list"),contains=c("SpatialPointsDataFrame"))
setClass("SpatialPointsDataFrameListZoo",contains=c("SpatialPointsDataFrameList"))
#setGeneric("as.yearmon")
as.yearmon.SpatialPointsDataFrameListZoo=function(x,...)
{
newlist=mapply(zoo:::as.yearmon,x@list,MoreArgs=list(...),simplify=FALSE)
x@list=newlist
return(x)
}
setMethod("as.yearmon",
signature(x = "SpatialPointsDataFrameListZoo"),
as.yearmon.SpatialPointsDataFrameListZoo
)
works for me (at least, it is installable and passes checks, if I add
Depends: methods, sp, zoo
into the DESCRIPTION file (hence without using a NAMESPACE yet).
