I am new to the RStudio Community. Recently, I have tried using the codes for 'Predicting Sunspot Frequency with Keras' by Matt Dancho and Sigrid Keydana and I bumped into an issue.
Whenever I try to run the line:
coln <- colnames(compare_train)[4:ncol(compare_train)] cols <- map(coln, quo(sym(.)))
RStudio will show the error:
Error in is_symbol(x) : object '.' not found
Did anyone face this issue as well? Could it be due to the updates on the packages involved?
The complete script can be found here:

Thank you! Any help would be much appreciated!
