The old(er) "ts" function in SPLUS has some advantages over new functions.
The main advantage I find - and still use it for this - is the formating:

When the time series is inserted in reports , it allows you to see
seasonality and year-over-year trends for particular months.
Nevertheless, that is only true when it is printed.
Does anyone have a simple way to create a matrix of that exact format?
I looked at the printing method - but that is hidden in C and could not
find a way to use it to return a matrix or data frame where:
- the rows would be named by the year
- the columns would be named after the month.
I can imagine a complex way of doing this (breaking the data by year,
making a matrix by appending rows, naming the rows and the columns, etc).
Is there something more trivial that I am missing?
Thanks,
Yannis Tzamouranis
