Re: [R] hist of dates

hist.Date is not exported from its namespace. Try RSiteSearch('namespace') to learn more about this (look for the R News article).

As you saw, hist() will dispatch hist.Date() when it is given a date-time argument. Read the docs again -- you failed to specify the breaks = ... argument properly.
