Question

[Mahan]

I'm running lassosum by following the steps on their github page.

I'm at the following step:

v <- validate(out, pheno=pheno) # Alternatively, specify the phenotype in the argument

I have supplied pheno from a dataframe as follows

v <- validate(out, pheno=pheno$status)

However I'm getting the following error. Can you please suggest why its happenin and how I can resolve it?
