error "undefined columns selected"

[lemontree]

Hi,

I have transformed the data for analyzing using the MDCEV model. I received the error Error in `[.data.frame`(database, , apollo_control$indivID) :
undefined columns selected.

Could you please help me to look at it?

Hi

does the column indivID exist in your data? You need to use the ID column from your data, which might be a different name
