Apply optimal Yeo-Johnson transformation to a numeric vector

Description

Finds the Yeo-Johnson transformation that minimizes the skewness of the vector. Returns the transformed vector with an attribute "lambda" (transformation parameter). Uses yeo.johnson.

Usage

YeoJohn(x, keepMedian = T, keepMAD = T, trim = 0)

Arguments

`x`	numeric vector to transform
`keepMedian`	Should the result be shifted so that it has the same median as the input vector?
`keepMAD`	Should the result be scaled so that it has the same dispersion (median absolute deviation) as the input vector?
`trim`	Numeric value between 0 and .5 . For robustness against outliers, this amount of each of the distribution's tails is excluded when estimating the optimal lambda.
