Your troubles with 'aggregate' for a ts are one of the reasons I created the
'tis' and 'ti' classes in the fame package. If you do this:
x1 - tis(1:24, start = c(2000, 10), freq = 12)
x2 - tis(1:24, start = c(2000, 11), freq = 12)
y1 - aggregate(x1, nfreq = 4)
y2 - aggregate(x2, nfreq = 4)

Just save the spreadsheet as a csv file and use tisFromCsv() in the fame
package. One of the arguments tisFromCsv() takes is a dateFormat, so you can
tell it what format the date column is in. You can also tell it the name of
the date column if it isn't some

The TimeIndex class in the 'fame' package handles this kind of stuff with ease.

a 'ti' object is a TimeIndex, and it has a tif (TimeIndexFrequency) embedded
in it.

As Gabor said, ts series are not good for weekly data. That's why I created the
tis (Time Indexed Series) class, in the 'fame' package. You don't need the
Fame database to use them.

Now, R does not have everything we want. One thing missing is a decent
R-DB2 connection, for windows the excellent RODBC works fine, but ODBC
support on Linux is a hassle.
A hassle? I use RODBC on Linux to read data from a mainframe DB2
The 64 bit version of VisualWorks Smalltalk has an immediate ShortDouble,
which sacrifices two bits of exponent for a tag. It thus has the same
precision as an IEEE double, but one fourth as much range. Overflows
automatically get promoted to ordinary Double's, which are pointers to objects
Look at the 'fame' package I recently put up. You don't need to have the FAME
database installed to use it. Among other things, the package defines a class
tis (Time Indexed Series) that can handle weekly time series.

The 'fame' package I submitted to CRAN can handle hourly, minutely, and
secondly series. The first submission I made last night did not build
correctly on a Linux machine without the FAME libraries, but the one I put up
this morning has fixed that. It should be available soon, unless I missed
