Hi Martin, Off hand I do not know of a pre-defined function to do it, but the "z-transformation" is just the inverse hyperbolic function, the mean is just the mean, and the back transformation is the hypoerbolic function so...
############ x <- c(.5, .4) tanh(mean(atanh(x))) ############ should do it.
