Question on model.matrix using BMTME Package

arlyna · September 2, 2021, 1:50pm

Hello, I am trying to design a matrix using model.matrix:

ZG <- model.matrix(∼0 + as.factor(phenoMaizeToy$Line))

However, I am receiving this error:

Error: unexpected input in "ZG <- model.matrix(∼"

Does anyone know how to mediate this issue?

Thanks!
