Sorry for confusing you all with my inexperienced posting . I tried as u said if you have 9 rows in the data it is working fine but please try out the same example as you have suggested earlier with morethan 9 rows.
I tried it as following datetime <-c( + "01OCT1987:00:00:00.000", + "12APR2004:00:00:00.000", + "01DEC1987:00:00:00.000", + "01OCT1975:00:00:00.000", + "01AUG1979:00:00:00.000", + "26JUN2003:00:00:00.000", + "01JAN1900:00:00:00.000", + "13MAY1998:00:00:00.000", + "30SEP1998:00:00:00.000", + "30SEP1998:00:00:00.000", + "30SEP1998:00:00:00.000", + "30SEP1998:00:00:00.000") dt <- as.data.frame(datetime) dt$date<-strptime(as.character(dt$datetime),"%d%b%Y") and got the following error : Error in `$<-.data.frame`(`*tmp*`, "date", value = list(sec = c(0, 0, : replacement has 9 rows, data has 12.
