The tis package has the ti (TimeIndex) class that does what you want,
and I modestly think it's nicer than the zoo stuff.
As for S4 classes, there's a good reason many of us don't use them:
they're too inflexible and hard to program with. I wouldn't go there
unless I really had to.

The main use for all this was so I could use quarters as index columns
with data.table, which demands integer storage mode. (This is part of
my ongoing attemp
Note that zoo's merge can handle that:
>> library(zoo)

Johann,
Following up on Gabor's reply, the mondate package (new on CRAN last week)
will accomplish your needs.

Dear List Members,
I'm struggling with the documentation of a generic S4 replacement method.
I've created a S4 method "lows" via
setGeneric("lows", function(object) standardGeneric("lows"))
setGeneric("lows<-", function(object, value) standardGeneric("lows<-"))
setMethod("lows", "myClass", func
Hello,
I'm trying to figure our why my package (cxxPack) fails to build
under Solaris using CC on CRAN, and I wonder if somebody can
comment?
If I try to build R on a Solaris SPARC box that has CC the
R configure script uses gcc/g++ instead of CC, yet CC seems
to be used for the CRAN builds.

The way R treats the first argument to an S3 method
which uses a different name for the argument than
the generic depends on whether there is a ... in the
argument list. If there is is no ellipsis then
the call cannot tag the argument with either name
but an untagged first argument works:

First I tried 'setenv R_SHELL /usr/local/bin/bash', as bash is the weapon
of choice for the faculty wishing to use R, then ran ./configure as before.
The ./configure output line
using as R_SHELL for scripts ... /usr/local/bin/bash
would seem to indicate that the R_SHELL environment variable was
Hi,
I just updated my R-devel today using the tarball from 2010-06-07

The table of content has:

but latter in the file, the referred sect
