The ExStatR plugin for biodiversity research based on Excel and statistical package R Novakovskiy A.B. Institute of biology Komi Science Center
Principal scheme of ExStatR XMLfile: Source data, captions, settings, etc. Excel source file Result diagrams Calculation in the “R” XMLfile: result tables Final results (diagrams and/or tables)
Designed algorithms • Heat Maps • Graphs • Circle form • Tree form • Star form • Connected components • Distances / similarities calculation • Euclidean, Manhattan diastances • Jaccard, Bray similarity indexes • Spearman, Pearson correlations • Cluster analysis • Single-linkage clustering • Complete-linkage clustering • Ward's method • UPGMA • Ordination • Principal component analysis (PCA) • Nonmetrical multidimensional analysis (NMS)
Conclusion • This add-on is easy to use and expands capabilities of Excel in the statistical analysis • This approach of data communication between Excel and R allows to implement new algorithms of data analysis fast and easy https://ib.komisc.ru/ExStatR The research was partly supported by the Russian Foundation for Basic Research and Government of Komi Republic (18-44-110015)
