Concentration transform
concentration_transform.Rd
Previously called concTransform. Helper function for plotting survey indices. This analysis makes it easier to transform X values that are concentrations. Because it is common to transform X values to their logarithms, which is required before fitting some models to your data. Since the logarithm of zero is undefined, if you enter X=0 that value will be empty (missing) after transformation. This analysis lets you substitute some other value (a tiny concentration) for zero before taking the logarithm.
