:exclamation: This is a read-only mirror of the CRAN R package repository. model4you — Stratified and Personalised Models Based on Model-Based Trees and Forests
When using the gettree() function, sometimes the following occurs:
gettree(My_Forest, 2)
Error in contrasts<-(*tmp*, value = contr.funs[1 + isOF[nn]]) :
contrasts can be applied only to factors with 2 or more levels
Yet when I run the same line again, it will extract and print the full tree without a problem. The error appears to be random - I used gettree() to extract the same tree 5 times, and the error appeared twice. The error noted above also appears if I try to run the varimp() function, which I assume is happening because it calls upon gettree(). I can try to generate a reprex if needed, but my data is from a clinical trial so I cannot share the existing content. Any help with this issue would be greatly appreciated.
EDIT: I didn't realize gettree() comes from partykit rather than model4you, but github won't let me delete the issue. I imagine you would still like to know this since it is a dependency for your package. Apologies for the error!
