biovolume()

Calculating biovolume is made easy with the biovolume() function. This method takes in a zoo_df and will return a vector of biovolumes for each row. There are two ways to calculate biovolume; sphere or ellipsoid Finally, to calculate biovolume, you must provide a pixel-to-mm conversion ratio.

library(EcotaxaTools)
zoo_df <- ecopart_example$zoo_files[[1]]
biovol <- biovolume(input = zoo_df,
                    shape = 'ellipsoid',
                    pixel_mm = unique(ecopart_example$meta$acq_pixel))
