Name  Age  Vaccination
A      12      yes
B      16      yes
C      12      no
D      19      no
F      21      yes

In this table, can someone tell me how should I write an R program to find out the mean of the age of people who have a vaccination status of YES?

Thank you

Try `mean(df$Age[df$Vaccination == 'yes']) [1] 16.33333` OR `with(df, mean(Age[Vaccination == 'yes']))` – Karthik S Jul 06 '21 at 12:46
`aggregate(Age ~ Vaccination, df1, mean)`. – Rui Barradas Jul 06 '21 at 12:46
