I'm attempting to run an LME model with random intercepts for location and have received an error message. The model and error message are given below: > mixed.distance <- lme (fixed= log(min5inpnc) ~ i93centerline, random=~1|location, data = nosmokecomp) Error in y[revOrder] - Fitted : non-conformable arrays I believe that my dataset may have dimensions that are not working with the model, but I'm not sure how to diagnose the exact problem. Can someone provide assistance? Thank you, Christina...
