Dear all I am trying to fit gam to my data but it keeps giving me errors.
It does not find the covariate ArrivalTime even though it is clearly defined in the data frame. It happens with any covariate that I put in the s() term... And not only for this data set, but for any dataset that I try to analyse. Do you have any idea why I can't run gam? I can run perfectly any other type of models (GLM, GLMM, ZIP...).. Any help would be appreciated. Thank you very much. Best Diego -- *Diego Pavón Jordán* *Finnish Museum of Natural History* *PO BOX 17 * *Helsinki.
