DescriptionEach of these txtfiles contains R code for calculating invertebrate secondary production. Differences among files are based on the different methods used to calculate secondary production, including the instantaneous growth method (igr.prod_function.txt), p:b ratio method (pb.prod_function.txt), and the size frequency method (sf.prod_function.txt). The get.dates_function.txt file is used to select a range of dates and sites, and the wrapper.site.yr_function.txt file is used to calculate production of multiple taxa at multiple sites using a variety of methods specified by the user. Questions should be directed to Dr. Benjamin J. Koch at [e-mail].
