Hi all,
this one left me a bit puzzled, as I don't seem to find a function to
perform this easily. I must have overlooked the obvious, so sorry in
advance.
I have a list of dates in numerical format (i.e. 34576), defined as
the number of days that passed since january 1st 1900. So I apply the
See ?weekdays, which says
Note:
Other components such as the day of the month or the year are very
easy to compute: just use 'as.POSIXlt' and extract the relevant
component.
so
as.POSIXlt(MyDate)$year+1900
[1] 1994
is how you are expected to do it.
