I just updated the `respfun`

package with three new functions:

https://github.com/nicholascarey/respfun

`eff_vol`

This calculates the ‘effective volume’ of a respirometer, that is the volume minus the volume of the specimen. This allows you to input the correct water volume into respirometry analyses in order to calculate the correct amount of oxygen used, for example in the `respR::convert_rate`

function.

`spec_density`

This function calculates a specimen density from a total wet mass and a buoyant mass

`wm_to_vol`

This is a simple function to convert a water mass to a water volume.
