Find the error

We went ahead and pre-loaded some code for you, but there's still an error. Can you trace it and fix it?

Fix the error by including code on the last line. Remember: you want to call mean() only once!

Prova a risolvere questo esercizio completando il codice di esempio.

# Don't edit these two lines
vec1 <- c(1.5, 2.5, 8.4, 3.7, 6.3)
vec2 <- rev(vec1)

# Fix the error
mean(abs(vec1), abs(vec2))
