#' Plot a simple algebraic equation with data
#'
#' \code{plotFunction_Data} plots an x-y relationship with data

#' @param x The independent variable
#' @param y The dependent variable
#' @param data two column of data to be plotted.
#' First column is independent variable. Second column dependent variable.
#' Must be a data.frame
#' @param x_label value for the x label axis
#' @param y_label value for the y label axis

#' @return A plot of your function
#' @examples
#' x<- 0:25
#' y<- x^2
#' data <- data.frame(Loblolly$age,Loblolly$height)
#' plotFunction_Data(x,y,data,'x','y')

#' @import ggplot2

  ### Do a line plot
