Hello everyone,
i try to identify the first element of a date vector, for which the following
condition holds: at least 3 more dates within the next 365 days, but at least
one of these must be between 3-12 month later.
dates = as.Date(sort(rnorm(10,3000,100)), origin = "2000-1-1")
Has anyone an idea how to do this economically? I'll need to apply this to a
large dataset with date vectors of various lengths and I can think only of
quite difficult algorithms :(
Any ideas would be appreciated,
Felix
