Hi, I upgraded to R-1.6.0 and I am facing the following error when loading a package I am working on. Error in mlistMetaName(f) : No way to associate a generic function with an object of class "NULL" Error in library(affy) : .First.lib failed This happen when I do cacheMetaData(as.environment(where)) in the .First.lib function Any hint ?

the code below has me confused: setClassUnion("index", c("numeric", "character", "logical")) extends("numeric") # i don't see the class union library(Matrix) extends("numeric") # now i see the class union i am aware that the "Matrix" package separately defines the "index" class union. is it the case that

...n from the .First.lib function in your package (ONLY needed if you have methods for primitives). The code needed is something like this (inside .First.lib, which gets a second argument "pkgname": where <- match(paste("package:", pkgname, sep=""), search()) cacheMetaData(as.environment(where)) (Extra calls to cacheMetaData shouldn't hurt, beyond a moderate bit of extra computation, so this should not be a disaster even after modifications to library()).

...e done to get rid of these warnings, which I believe in the case "unloadNamespace" case are irrelevant. The stack of calls is: # where 3: sapply(where, getPackageName) # where 4: findClass(what, classWhere) # where 5: .removeSuperclassBackRefs(cl, cldef, searchWhere) # where 6: methods:::cacheMetaData(ns, FALSE, ns) # where 7: unloadNamespace(pkgname) So for instance: >findClass('data.frame', getNamespace('data.table')) generates a warning which once again seems irrelevant. On the top of my head, I could imagine adding an extra argument to getPackageName, say warning = TRUE,...

please see the code below. foo2 fails to dispatch correctly, but foo does fine. i have tried 'cacheMetaData(1)' and a number of different variants of 'cacheGenericsMetaData', on the possibility there is a caching issue. but i still can't sort it out. also one general question: does it really matter what's in the body of the function definition in a 'setGroupGeneric' ca...

...aker. I should not need to reload my package to check validity of something like 'character'. In my actual use case I had a class that contained 'character' among other things that I was checking with `validObject(..., complete=TRUE)`. I attach a patch that adds a cleanup step to `cacheMetaData` which is kicked off by the package unload process. I grant I'm not an expert in these matters and there could very well be an important use case where removing the references is undesirable. This brings us to the second issue: even if the first patch is undesirable, `validObject` fails while...

Hi, I have a BioC infra-structure package that works fine (I can build, check and load it successfully) on revision r53950. The very same package fails on r54591 with the error below: Error in loadNamespace(package, c(which.lib.loc, lib.loc), keep.source = keep.source) : cyclic name space dependency detected when loading ?oligoClasses?, already loading ?oligoClasses? I don't see anything

Dear R-Devel subscriber, as a follow up to my yesterday's email: I tested an analogous example with the S4-package "flexclust" by executing the following code: library(flexclust) example(cclust) cl After saving the work space and starting a new R process with the restored work space, the same behaviour (i.e., the methods pertinent to "flexclust" are not used, even after
