Hi Sascha,
As Uwe said, I am not sure you will get more elegant. If you want it
to be simple because you do it a lot and the typing is a burden,
consider writing a function. Here is a little example:
##########
f <- function(x, y, ...) {
mx <- mean(x, ...)
my <- mean(y, ...) * c(-1, 1)
mx + my
}
f(rnorm(10), runif(10))
##########
