BoxCox Transformation

[samkelomotsa]

I have data that is not normally distributed and I want to perform a BoxCox transformation on the data set for "traitx". How can I write a code which can help me transform the data. I've included a sample of the data set below. "Breed" and "traitx" being are independent and dependent variable respectively.
