Hi everybody,
i have a csv-file, containing dates in an akward sas format, where
31.12.1559 is -1, 1.1.1960 is 1, 2.1.1960 is 2 and so on (see http://www.sfu.ca/sasdoc/sashtml/lrcon/zenid-63.htm
). Is there any function in R to convert this into YYYY-M-D easily?
Seems as though as.Date should do it, assuming that's a typo for the
first date. You just need to change the default origin setting:
> as.Date( c(-1,0,1), origin="1960-01-01")
[1] "1959-12-31" "1960-01-01" "1960-01-02"
Best,
Felix
