#'Compute Power for Comparing Two Dependent Correlations, No Variables in Common
#'Takes correlations and range of values. First variable in each pair is termed predictor, second is DV
#'@param r12 Correlation between the predictor and DV (first set of measures)
#'@param rxy Correlation between the predictor and DV (second set of measures)
#'@param r1x Correlation between the predictor (first measure) and the predictor variable (first measure)
#'@param r2x Correlation between the DV (first measure) and the predictor variable (first measure)
#'@param r1y Correlation between the predictor (first measure) and the dependent variable (second measure)
#'@param r2y Correlation between the DV (first measure) and the dependent variable (second measure)
#'@param nlow Starting sample size
#'@param nhigh Ending sample size
#'@param by Incremental increase in sample size from low to high
#'@param tails one or two-tailed tests (default is 2)
#'@param alpha Type I error (default is .05)
