Description Usage Arguments Details Value Author(s) See Also Examples

This function calculates Foraminifera biovolume, through geometric approximation. To compute others organisms cell volume use volume.total function

1	bio.volume(data, pco = 0.76, genus = NULL, model = NULL)

`data`	a numeric vector or data frame with size data. Size data parameters by model see `volume` details.
`pco`	(optional) vector informing percent of cell occupancy in the test. Default value set for specific genus in `data_pco`.
`genus`	(optional) character informing foraminifera genus to calculate individual biovolume. See all genera available in `data_pco`
`model`	(optional if genus unknown) character informing geometric model to calculate volume. See all models available in `volume.total`

The function calculates the biovolume of different individuals from the available genera.

A 'data.frame' or numeric object, consisting of calculated individual volume (if not available), biovolume and model (if genus is informed).
