...Xct https://svn.r-project.org/R/trunk/src/library/grDevices/R/prettyDate.R there is currently a "pretty" time step listed as "15 DSTdays"... but this actually doesn't line up well with months. Much better to implement directly what this is trying to do: i.e. to have a "halfmonth" time step. This is just the union of two "monthly" sequences, one on the 1st of each month and another on the 15th of each month. With this in place we have: prettyDate(as.Date(c("2002-02-02", "2002-05-01"))) # [1] "2002-02-15" "2002-03-01"...

...unctionality is already included in lattice 0.18-5, which was released with, and depends on, R 2.11.0. (There is one known issue: the Date method in lattice 0.18-5 can miss a tick at one end of the axis if your local time zone is not "GMT". Also that version does not include the new "halfmonth" time step.) -Felix -- Felix Andrews / ???
