Hello,
I am trying to calculate predicted values derived from one dataset into a
hypothetical dataset. I tried this line of code:
graphdata$fmgpredvalues <- predict(Acs250.3.4, graphdata)
and received the following error message:
ERROR: ZXend[1], drop = FALSE] %*%lmeFit$beta
I have made sure all variable names are the same between the two datasets and
all factors are appropriately labeled.
I appreciate any insight.
Thanks,
Brittany
