Is this a documentation bug? Spss dates import
...df$MYDATE , origin="1582-10-14"))
But if you take a look at the vector test.df$newdate you got:
R.date = SPSS.date - 1 day
Please confirm this! I would like to be sure that i didn't made mistakes (I've
used SPSS 11 + R 2.8)
If you come back to data, changing 14 to 15
test.df$newdate2 <- as.Date(as.POSIXct(test.df$MYDATE, origin="1582-10-15"))
assures that
R.date = SPSS.date
> test.df
MYDATE newdate newdate2
