[Rd] callNextMethod() doesn't pass down arguments

Hi, According to its man page, callNextMethod() (called with no argument) should call the next method "with the arguments to the current method passed down to the next method". But, for the "[[" and "[" generics (primitives), the argument after the dots doesn't seem to be passed down: setClass("

[Rd] "names<-" doesn't raise an error

Hi, When a method is not defined for an object, you expect to get an error. But this is not the case for "names<-". You can use "names<-" on any S4 object: it will remain silent, giving you the impression that it actually did something: setClass("A", representation(vals="numeric")) setMethod

[Rd] bug in classesToAM()

Re: [Rd] formal argument "envir" matched by multiple actual arguments

In fact reg.finalizer() looks like a dangerous feature. If the finalizer itself triggers (implicitely or explicitely) garbage collection, then bad things happen. In the following example, garbage collection is triggered explicitely (using R-2.9.0): setClass("B", representation(bb="environment

[Rd] Inaccuracy in ?convolve

Hi, Man page for 'convolve' says: conj: logical; if 'TRUE', take the complex _conjugate_ before back-transforming (default, and used for usual convolution). The complex conjugate of 'x', of 'y', of both? In fact it seems that it takes the complex conjugate of 'y' only which is OK
