Is there any way to get a numerical summary of the values of a difftime object? E.g.
TimeToWean <- difftime(WeanDate, BirthDate, units = "days")
I can repeat
sum(TimeToWean == 20)
with as many other values are needed to build up a frequency table, but is there a simpler way in R version 1.8.1?
Are you looking for table() ?
