 Hello, I have some problems in using chron, Hmisc, and lattice. First,

   print(plot.a)
 Error in pretty(rng, ...) : unused argument(s) (format.posixt = NULL)

This one is a bug in lattice (there is some code to support chron
objects, but evidently not many people use it). I will include a fix
in the next update.

[R] format.dates, chron and Hmisc

Hello, I have some problems in using chron, Hmisc, and lattice. First,

+  })
 print(plot.a)
Error in pretty(rng, ...) : unused argument(s) (format.posixt = NULL)

In both cases, the cron objects have been created using the function 
chron(). Are lattice and Hmisc functions incompatible with chron, or am 
I doing something else that causes these problems? Thanks, Ruud
