The first function ymd(): parses the date as the year, month, and date format
x <- c("09-01-01", "09-01-02", "09-01-03")
ymd(x)
[1] “2009-01-01” “2009-01-02” “2009-01-03”
x <- c("2009-01-01", "2009-01-02", "2009-01-03")
ymd(x)
[1] “2009-01-01” “2009-01-02” “2009-01-03”
> ymd(090101, 90102)
[1] “2009-01-01” “2009-01-02”
Similar to this function are ydm(), mdy(), mdy(), myd(), dmy(), dym(),
Note: The three English letters ymd here represent year, month, and day respectively. The different letter arrangements above mean that the date is parsed in different formats.
The year, month and day of the extraction dates
