Read ?mean.
Look at the argument list.
The mean function only applies to the first argument.

dd1 <- 50

Read the help page ?mean. You are specifying the parameters x and trim.

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

Hi all,
I got one intresting problem with caliculating mean that is
while i am taking mean of values
*0.6, -0.8, 4, -3.8*
using
*val-c(0.6, -0.8, 4, -3.8)*
*mean(val)*
it given result as
*2.775558e-17*
but the actual result is *0*
can any one suggest how can I get correct mean result in this
