#' Prepare a DTSA-II Monte Carlo PhiRhoZ.csv file for plotting
#'
#' Use the results from DTSA-II Monte Carlo simulations that
#' produce a PhiRhoZ.csv file to create an R dataframe for
#' plotting. Note: this file is TAB delimited and has two
#' header lines and so needs some cleanup...

#' @param inDir A string containing the directory with the
#' PhiRhoZ.csv file. Terminate with a '/' !!!
#'
#' @param fName A string. Default is 'PhiRhoZ.csv'

#' @return a dataframe

#' @keywords keywords
