I fit a random effects linear model to data, and then tried to use it to predict, but I got this error:
predict(lmeObject, newdata, level=0)
Error in eval(mCall$fixed)[-2] : object is not subsettable This is a new error for me. It still occurs if I change the level to 1 or if I change the data for prediction back to the original dataset to which the lme model was fitted. Can anyone help? Thank you in advance! Rebecca
