One must specify that there is a header if there is one, each % item
should only
be listed once, and format is currently only used for "Date" class so
you want to
use the FUN= argument -- although in the development version of zoo format is
availailable more generally. Here are several ways to do this. z1 is
created using
chron, z2 uses POSIXct and the z3 uses POSIXct and the new version of read.zoo
in the devel version of zoo.
