How to store specific values from a data frame to a variable in R?

Question

I have a data frame with 'Age' column and its values are as below:

Age 12 15 16 20 23 24 20 15 16 20 26 20

I want to create a variable and store in it the count of 20 i.e number of people with age as 20.

Can someone please tell me how to do this in R?

See table(myDatat$Age) function

If you have a data frame called data with a column age, you can do this:

count <- sum(data$age == 20)

zx8754's answer table(myDatat$Age) is probably better as it gives you data about all ages, but this is better if you want to return a number rather than a table.
