You want to calculate mean of the two vectors (vec1 and vec2). Copy and paste the following codes. The last line will give you an error message. Fix the error in the last line.

# 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))

*****HINT: In your RStudio, check the syntax of mean by using this: ?mean

You will find that mean only take one argument. How do you combine two values into one?
