Converts any of the following character forms to a Julian date:
8/31/56, 8-31-1956, 31 8 56, 083156, 31Aug56, or August 31 1956.
Usage
as.date(x, order = "mdy", ...)
Arguments
x
input data vector.
order
if x is character, defines the order in which the
terms are assumed to appear in a xx/xx/xx date. The default is
month/day/year; any permutation of mdy is legal.
...
if x is character, then any other arguments from
mdy.date() can be used as well.
Value
For each date, the number of days between it and January 1, 1960.
The date will be missing if the string is not interpretable.
Details
If x is numeric, then floor(x) is returned, e.g.,
as.date(35) is the same as as.date(35.2) and gives
February 5, 1960 (5Feb60). If x is character, the
program attempts to parse it.
