I have this dataset with two columns and four rows
x <- c(-1, -2, 2, 3)
y <- c(0, -3, 2, -2)
cbind(x, y)
I want to sum the absolute values of columns x and y using dplyr and add results in column z. It should look like this
z <- c(1, 5, 4, 5)
cbind(x, y, z)
I have tried using mutate and place the argument abs in different positions of a command but nothing works.
Can anyone help this R beginner solve this apparent simple problem?
Thanks,
