rray_mean: Calculate the mean along an axis

In DavisVaughan/rray: Simple Arrays

Description

rray_mean() computes the mean along a given axis or axes. The dimensionality of x is retained in the result.

Usage

rray_mean(x, axes = NULL)

Arguments

x	A vector, matrix, or array to reduce.
axes	An integer vector specifying the axes to reduce over. 1 reduces the number of rows to 1, performing the reduction along the way. 2 does the same, but with the columns, and so on for higher dimensions. The default reduces along all axes.

Value

The result of the reduction as a double with the same shape as x, except along axes, which have been reduced to size 1.
