### A piper diagram based on the ternary plot example here: http://srmulcahy.github.io/2012/12/04/ternary-plots-r.html
### This was written quickly, and most likely contains bugs - I advise you to check it first.
### Jason Lessels jlessels@gmail.com

### This now consists of two functions. transform_piper_data transforms the data to match 
### the coordinates of the piper diagram. ggplot_piper does all of the background.


transform_piper_data <- function(Mg, Ca, Cl,SO4, name=NULL){
  if(is.null(name)){

function (data, group = NULL, colours = NULL, pch = NULL, numbersymbols = FALSE,

{
    p <- (X/11)
    q <- (X/22)
    over100 <- data[data$Ca + data$Mg > 100 | data$Cl + data$SO4 > 
        100, ]

### Aim: To test the significance of randomly allocating flow to 'midnight' water quality samples.
### Date Created: Thursday 2nd September 2010
### Author: Jason Lessels
### Packages required: TSAgg_0.2-1,geoR 
### Notes: The script can easily be modified for the other water quality parameters, and the amount of simulations. Things to check:
###Both WQ and discharge must have the same initial time stamp (hours) before aggregation.
###WQ variable modify lines 52,60,146,186
###line 99 changes the amount of simulations to run.
###line 156 determines when the bushfire occurred.
