number of patients in a hospital on a given date
Dear R-users!
I am using R 1.7.0, under Windows XP.
Having some hospital discharge data (admission date and discharge date for
each patient), I want to get the number of patients in the hospital on a
given date.
My data look like (simple example):
> x <- data.frame(patid=c("pat1", "pat2"), adm.date = c("15.03.2002",
"16.03.2002"),
