[R] Calculate mileage at each 'faildate'

Hi R-helpers, - I have a dataframe similar to 'simD'. > dput(simD) structure(list(ID = structure(c(1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L), .Label = c("A", "B"), class = "factor"), PRODDATE = structure(c(14655, 14655, 14655, 14655, 14664, 14664, 14664, 14664, 14664, 14664 ), class = "Date"),
