Dear useRs,

the new version 1.2-0 of the zoo package for dealing with regular and
irregular time series data is available from the CRAN mirrors.

This version includes two important changes/enhancements:

  - rapply() was re-named to rollapply() because from R 2.4.0 on,
    base R provides a function rapply() for recursive (not rolling)
    application of functions, which was already described in the Green
    Book. zoo::rapply() currently still exists for backward
    compatibility, however, it is flagged as deprecated and now
    dispatches to rollapply() methods. We recommend to change existing
    scripts from using rapply() to rollapply().

  - xyplot() methods for "zoo", "ts", and "its" objects have been
    added for creating trellis time series graphs. The functions
    are still under development and suggestions for improvement are
