> c(10485849600,10477641600,10561104000,10562745600)+ISOdate(1582,10,14) [1] "1915-01-26 13:00:00 CET" "1914-10-23 13:00:00 CET" [3] "1917-06-15 13:00:00 CET" "1917-07-04 13:00:00 CET" Does this look right? (If you don't want the times, use as.Date). BTW: There's a strange asymmetry: > ISOdate(1582,10,14)+ > c(10485849600,10477641600,10561104000,10562745600) [1] "1915-01-26 12:00:00 GMT" "1914-10-23 12:00:00 GMT" [3] "1917-06-15 12:00:00 GMT" "1917-07-04 12:00:00 GMT" (have we seen this before?). -- O__ ---- Peter Dalgaard Øster Farimagsgade 5, Entr.B c/ /'_ --- Dept. of Biostatistics PO Box 2099, 1014 Cph.
