When I run cut.Date or cut.POSIXt with argument breaks
= "weeks", the function gives the first day of that
week, unless the date is the first day of the week, in
which case it gives an error message as in:
> cut(as.Date("2006-08-16"), "week")
[1] 2006-08-14
Levels: 2006-08-14
> cut(as.Date("2006-08-14"), "week")
Error in 1:(1 + max(which(breaks < maxx))) :
result would be too long a vector
In addition: Warning message:
no non-missing arguments to max; returning -Inf
> sessionInfo()

Bug or feature?
