How to calcuated overall-mean in R

Assume I have the following multivariate

x <- MASS::mvrnorm(10, rep(0,3), diag(3))  

I want to calculate the overall-mean for different subsets. My attempt as follows:

x_barbar <- NULL  k = 1  for(i in 1:5){   x_barbar[i] <- mean(x[k:(k + 1), ])   k = k + 2  }  

Another statistic that I am interested in calculating is the overall-mean for observations (1,3,5,7,9) then for observations (2,4,6,8,10)

What is the best and concise way of calculating those two different statistics? your help is appreciated.
