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 yearqtr class already rounds off automatically to avoid floating

The main use for all this was so I could use quarters as index columns

Johann,
Following up on Gabor's reply, the mondate package (new on CRAN last week)
will accomplish your needs.
I'm trying to make an integer-backed quarter (as in fraction of year)
class, but I can't quite it to work. I want integer-backed so I don't
have to worry about floating-point effects
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, function(object)

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

The ./configure output line

Hi,
I just updated my R-devel today using the tarball from 2010-06-07

of content at the top of R_HOME/doc/manual/R-admin.html is broken.
The table of content has:
