Hello,
The first argument of mean is a vector, the dots argument is to be
"passed to or from other methods." (from ?mean)
Try instead
mean(c(dd1, dd2))
Hope this helps,

Either I am doing something very stupid or my R installation has a glitch. What
am I missing?
dd1 <- 50
dd2 <- 54
mean(dd1, dd2)
[1] 50 # wrong
(dd1 + dd2)/2
[1] 52 # correct
aa <- c(48, 52, 56, 54, 52)
mean(aa)
[1] 52.4 # correct
