[Rd] NAs and weighted.mean

R-developers, In version R 2.11.0, weighted.mean was changed such that: > weighted.mean(NA, na.rm=TRUE) [1] 0 rather than NaN as in previous versions of R. I see a note in the NEWS file indicates that weighted.mean was changed "so an infinite value with zero weight does not force an NaN result."

Re: [Rd] format: different S4 behavior in a package

Thank you, Martin. That worked. And fyi 'export(format)' alone was not sufficient. Best, Dan On Wed, Jun 23, 2010 at 5:15 AM, Martin Morgan wrote: > On 06/23/2010 12:16 AM, Daniel Murphy wrote: > > R-Devel-ers: > > > > I have an S4 method that simply formats an object: > > > > setGeneric("format

[Rd] seek() and gzfile() on 32-bit R2.12.0 in linux

Peter, thanks for your comments. The reason I have taken this issue to R-devel is from the advice of Kurt Hornik. An update to my package oro.nifti is being refused by CRAN because it fails on the _development_ version of R on 32-bit linux. As we have just discussed (and thanks to Matt's input),

[Rd] format: different S4 behavior in a package

R-Devel-ers: I have an S4 method that simply formats an object: setGeneric("formatMe", function(x) standardGeneric("formatMe")) setMethod("formatMe", "ANY", function(x) format(x)) If I issue the above in an R session, then define an S4 class with its own format method, I get the desired result:
