| cut.POSIXt {base} | R Documentation |
Method for cut applied to date-time objects.
cut(x, breaks, labels=NULL, start.on.monday=TRUE)
x |
an object inheriting from class "POSIXt". |
breaks |
a vector of cut points or number giving the number of
intervals which x is to be cut into or an
interval specification, one of "secs", "mins",
"hours", "days", "weeks", "months"
or "years".
|
labels |
labels for the levels of the resulting category. By default,
labels are constructed using "(a,b]" interval notation. If
labels = FALSE, simple integer codes are returned instead
of a factor.
|
start.on.monday |
logical. If breaks = "weeks", should the
week start on Mondays or Sundays? |
A factor is returned, unless labels = FALSE which returns
the integer level codes.
