Transforms Pearsons correlation coefficients into z scores using Fishers method.

rho

Integer or numeric vector of Pearson's correlation coefficients

Fisher's transformation is when correlation coefficients are transformed into a z score. These z scores have an approximately normal distribution.

## Create integer or list of Pearson's correlation coefficients.

library(MASS)
rhoV <- as.vector(cor(t(mvrnorm(10,rep(3,100),diag(100)))))

## Determine Fisher-Transformed z scores of rho
zV <- fishersTrans(rhoV)
