bio.volume {forImage}

Biovolume calculus

Description

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

Usage

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

Arguments

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

Details

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

Value

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

Examples

# Calculate biovolume for different genera
#Ammonia size data
data("ammonia")

bio.volume(ammonia, genus= "ammonia")

# Calculate biovolume for unknown genus
df <- data.frame(h = 10, d_one = 10,
d_two = 10, area = 10, width = 10, length = 10)
bio.volume(df, model = "10hl", pco = 0.76)
