calculate.MR: Calculation of Metabolic Rate

In FishResp: Analytical Tool for Aquatic Respirometry

Description

The function is used to calculate and plot background respiration, absolute and mass-specific metabolic rates.

Usage

calculate.MR(slope.data, density = 1000,
             plot.BR = TRUE,
             plot.MR.abs = TRUE,
             plot.MR.mass = TRUE)

Arguments

slope.data	a data frame obtained by using the function extract.slope
density	numeric: the density of an animal body (kg/m^{3})
plot.BR	logical: if TRUE, the graph of background respiration rate is plotted
plot.MR.abs	logical: if TRUE, the graph of absolute metabolic rate is plotted
plot.MR.mass	logical: if TRUE, the graph of mass-specific metabolic rate is plotted

Value

The function returns a data frame with calculated background respiration, absolute and mass-specific metabolic rates. The data frame is used in the function export.MR.

Examples

# if the data have been already loaded to R,
# skip the first two lines of the code:
data(SMR.slope)
data(AMR.slope)

SMR <- calculate.MR(SMR.slope,
                    density = 1000,
                    plot.BR = TRUE,
                    plot.MR.abs = TRUE,
                    plot.MR.mass = TRUE)

AMR <- calculate.MR(AMR.slope,
                    density = 1000,
                    plot.BR = TRUE,
                    plot.MR.abs = TRUE,
                    plot.MR.mass = TRUE)
