Re: [Rd] (PR#7976) split() dropping levels (was "boxplot by factor")

2005-07-13 Thread Martin Maechler
I have now committed the new split(x, f, drop = FALSE) to R-devel --- entailing non-backward compatible behavior, but consistency with factor indexing (and with S-plus) --- split() and "split<-" and unsplit() functions and methods to R-devel. This does automatically fix the original posters "b

2005-07-13 Thread ripley
You need to call as.data.frame.table directly here. If we alter the generic we would need to alter all the many methods too (including those in various CRAN packages), and I am not sure this would be worth it (rather than clarifying the documentation). This was a user-contributed enhancement th

I think it is essential that the program which 'we' are trying to interface from R is under active development. I guess that it would also be 'politically wise' (and potentially useful) to ensure that the people behind Maxima and/or Yacas and/or ... find that it would be a good idea to interface

[Rd] Building R sources on Windows

Following considerable off list discussion, I will post this on the list in the hope that it may help others who experience the same grief I did getting R sources to build on Windows. Firstly there is just no way that, starting with a clean version of Windows 2003 server, and following the i

Hi guys another option would be David Gillespie's "calc", which is written in emacs lisp. This is a stable system with (AFAICS) as large user base. Unfortunately, it doesn't seem to be actively developed, as the last stable version (2.02f) appears to be 1996. I don't know if this would be
