For example:
sapply(cars[2:3], FUN = IQR)
But how about if I wanted index 2 and 5? Also instead of indexes is there any way to use the column names instead?
We can use anonymous function
sapply(names(cars)[1:2], function(x) IQR(cars[[x]]))
If we wanted columns 2 and 5, use c
instead of seq operator (using a different dataset as cars
have only two columns)
sapply(mtcars[c(2, 5)], IQR)
# cyl drat
# 4.00 0.84
