shinyNORRRM: A Cross-Platform Software to Calculate the CIPW Norm

Abstract In this paper, a novelty-free software to assess an efficient CIPW Norm (± 0.006 wt.% in differences between input and output data) is presented. The package available the official repository for user-contributed R packages (CRAN: Comprehensive Archive Network). able handle big data sets considers minor trace element compositions. algorithm can calculate odd minerals igneous rocks, such as cancrinite calcite, adjust Fe +3 /Fe +2 ratio different standard approaches, recalculate compositions of rocks anhydrous basis (100 ± 0.003 volatile-free adjusted). Furthermore, calculates several petrological parameters, graphical outputs are displayed following IUGS scheme standards. prime aspect shinyNORRRM symbiosis native functions with package’s shiny (Web Application Framework R) run norm user-friendly interface. be executed any operating system requires no previous programming knowledge, thus promising universal computational program matter. printed comma-separated values (*.csv) format, which highly compatible general spreadsheet editors. work, our validated using already compiled whole-rock geochemical databases.
