I'm trying to select a model under PCA using independent contrasts. Since PICs need to be forced through the origin I've been using lmorigin for the original regression, but it doesn't appear that stepAIC recognizes it. I keep receiving an error message - "Error in na.fail.default(list(Phenology = c(NA_integer_, NA_integer_, : missing values in object"
I'm having trouble navigating around this error message, and any suggestions would be appreciated. Thanks!
