Get year from date in R

In Order to get year from date in R we will be using as.numeric () and Format() function. Let’s see how to get year from date in R with an example.

### Create Data Frame

df1 = data.frame (
  Name =c('Annie','Catherine','Teresa','Peterson','Richard','joe'),
  Date_of_birth = as.Date(c('1995-06-16','1991-04-19','1993-07-22','1990-03-26','1991-05-12','1992-09-13')))
