hasSummary
  • This publication contains tools for statistical evaluation and exploration of data published by Radosavljevic et al. (2016). These data contain bulk geochemistry data (total organic carbon, nitrogen, stable carbon isotope) and granulometry of nearshore samples in the vicinity of Herschel Island, Yukon, Canadian Beaufort Sea. In addition, the functions of the script herein provide a means for summaries and comparison with terrestrial (Couture, 2010; Tanski et al., 2017; Obu et al., 2016) and marine (a subset of Naidu et al., 2000) data. The tools are contained in a script written for the R software environment for statistical computing and graphics. The script (sediments_geochemistry_plots_and_summaries.r) is richly documented and explains the functionality. Each data file also contains a description of the data in a comma separated file (csv). The functions of the script are: myinteract() - interactive mode mysum() - provides numerical summaries for WBP and TB, a box plot and runs a Two-sided Mann-Whitney-Wilcoxon test myloc() - provides numerical summaries and comparisons among the current study, marine, and terrestrial samples, a box plot and runs a Two-sided Mann-Whitney-Wilcoxon test myseds() - provides numerical summaries and comparisons of grain size data among the current study mycums() - plots cumulative frequency curves of grain size distributions by transect The package contains (included in the zip folder): sediments_geochemistry_plots_and_summaries.r - script file geochemistry_data_including_other_studies.csv - contains data by Radosavljevic et al. (2016) and other studies in the region VolFrequenciesCoordsTransects.csv - contains volumetric grain size frequencies granulometry_stats.csv - contains summary statistics of grain size data TransectSampleIndex.csv - provides an index of transects TransectMap.png - an overview map of sample transects
