median time period
Hello List
I'm trying to calculate the median period (in months) of a set of time intervals (between two interventions).
I have been playing with the lubridate package to create the intervals but I can't think of the right approach to get the median timeperiod.
Toy code:
library(lubridate)
test <- c('08-04-22', '08-07-28', '09-03-02', '09-03-03',

Typical - you post to the list and then work it out for yourself!
Anyway here's my solution
Toy code as before then:
intervalsMonths <- 12 * intervals$year + intervals$month
#convert whole years to months then add the remaining months for that entry in intervals
medianMonths <- median(as.numeric(intervalsMonths))
Best
