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", ...)
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.
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.
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.
