Hi all, I have problems with years of dates using "chron" package. I don't understand why R by this istruction: > dates("01/02/29",out.format="d/m/year") [1] 02/Jan/2029
> dates("01/02/30",out.format="d/m/year") [1] 02/Jan/1930 reads "29" as 2029 and "30" as 1930. How could I change to read "00" to "05" like 2000 to 2005 and "06" to "99" like 1906 to 1999 ?
