[Rd] foreign: write.xport

I see in the archives significant discussion about SAS, CDISC formats etc. for FDA, but no direct suggestion of adding a write.xport method to the foreign package. Are there significant barriers to doing so? [[alternative HTML version deleted]] ___

Re: [Rd] setGeneric() gives "must supply skeleton" when checking package

Martin, I added "importFrom(reshape, cast)" to NAMESPACE; package now survives R CMD check. Thanks for your help! -Tim On Sun, Feb 3, 2013 at 12:36 PM, Martin Morgan wrote: > On 02/02/2013 02:34 PM, Tim Bergsma wrote: > >> r-devel, >> >> In a development ve

[Rd] setGeneric() gives "must supply skeleton" when checking package

ms to suggest that no function skeleton is needed when creating a generic for a function defined in some other package. I found one or two previous related posts, but no obvious resolution. Comments appreciated, Tim Bergsma, PhD [[alternative HTML version deleted]] __

Re: [Rd] how to properly extend s3 data.frames with s4 classes?

Dear Ulf Martin, Thank you for your thoughtful analysis regarding the use of S3 data frames in S4. I asked the same question (in a more rudimentary manner) on the r-help list on 30 Nov 2006 and 04 Dec 2006. There were no replies. If you find a solution, please post. Best Regards, Tim

[Rd] prevent reassignment of function names

Hi. I'm trying to find a systematic way to prevent assignment to names of existing functions. I've tried reassigning to the assignment operator, with mixed results. The function definition for "<-" below works as hoped for the demonstrated assignments to a and c. However, for the assignment
