I'm working on a dataset that comprises information about children aged 0-4. I would like to calculate the date they turned the age of 5.
My dataset looks like this:
data = data.frame(
id = c(1:4),
Date_of_Birth = as.Date(c("2005-10-10", "2006-11-05", "2007-11-15", "2008-12-12"))
)
Then, I need to create a new variable 5y_birthday that gives me the exact date that those children turned 5y.
Can anyone help me to solve that?
