Re: [Rd] cut.Date and cut.POSIXt problem

2008-03-18 Thread Roger D. Peng
Seems changes in r44116 force the interval to be single months (or years) instead of whatever the user specified. I think the attached patches correct this. Interestingly, 'cut' and 'seq' allow for the 'breaks' specification to be something like "3 months" but the documentation for 'hist' does

By the way, it would be nice if the breaks argument accepted the word "quarter" directly since its quite a common break to need when using dates. On Tue, Mar 18, 2008 at 2:29 PM, Gabor Grothendieck <[EMAIL PROTECTED]> wrote: > I am using > > [1] "R version 2.6.2 alpha (2008-01-26 r44181)" > > and

[Rd] Utilities for methods

2008-03-18 Thread John Chambers
The first implementation of the methods package used the "MethodsList" class for method dispatch. Objects from the class stored methods recursively by the separate arguments in the method signature. That was a good structure for selecting a method, but not for most other utilities. However,

cut.Date and cut.POSIXt indicate that the breaks argument can be an integer followed by a space followed by "year", etc. but it seems the integer is ignored. For example, I assume that breaks = "3 months" is supposed to cut it into quarters but, in fact, it cuts it into months as if 3 had not been
