Hello everyone.
I am very much a beginner with R and I am trying to turn the following if-then
statement into R code. More detail. I want to create a new variable: "inperiod"
that will be a numeric code. So if a specific event start date (StartDate) is
greater or equal to a testing date (Beg1Date) AND the event end date (EndDate)
is less than or equal to the testing date (Beg1Date), I want the inperiod code
to be 1. I will do this for a range of dates so that the code can be anywhere
from 1-25.
If StartDate >= Beg1Date & EndDate <= Beg1Date inperiod = 1.
Thanks for any help.
