Groundwater Data Presentation and Interpretation

Contains one function for drawing Piper diagrams (also called Piper-Hill diagrams) of water analyses for major ions.


  • Version 0.6-1
  • added function testData to generate samples for creating piper objects

  • removed 'WaterType' and 'object' slots on piper objects because the concept was buggy. Better to assign pch and col parameters directly, example changed to reflect this.

  • fixed default pch and col assignment so more than 26 samples does not cause an error

  • Version 0.5-1
  • allowed use of `cex' parameter in piper diagrams
  • Version 0.4-1
  • fixed a bug that plotted points in the wrong places
  • Version 0.2-3
  • fixed a bug whereby cex parameter could not be used
  • Version 0.2-2
  • major rewrite as S4 classes
