[R] how to get a histogram of an POSIXct vector ?

search on web indicates that R also includes a hist method on POSIXct vectors.

My (perhaps too unexperienced) approach below yields an error.

Could somebody give me a hint what's wrong ?


> str(samples)

`data.frame': 7500 obs. of 1 variable:
 $ DateTime:'POSIXct', format: chr "2006-07-20 00:10:08" "2006-07-20 00:11:17" "2006-07-20 00:11:23"


Error in hist.default(samples) : 'x' must be numeric
