Data type on phenotype

[Shinezhuxin]

Dear professor

Recently, I want to use this package for investigate fitness landscape. But I have puzzle on how to present suitbale data for phenotype. If I use enzymetical activity as phenotype data, I directly use their activity vaule to express its phenotype data. However, If the phenotype data is enantioselectivity (ee) that two types of data, namely, R or S, I want to know what type of data expression is suitful for using this package. I hope some suggestions I would obtain. Thank you very much.
