Warning Column 'NETIDnode' does not exist to remove

https://github.com/osofr/tmlenet/blob/13cfc44f0e00da6dd45e55bb8bc56640a2fcb296/R/tmlenet.R#L485

This line references NETIDnode, which is not in this dataset. The variable name is Net_str in the data set. Is this supposed to remove the network IDs from the data set?
