The lost of two functions while running the codes

[catalystforyou]

Thank you so much for providing the code, but when I tried to run the predicting program in RStudio, some errors just happened. In analysis.R, line 860, the function "sortLvls.fnc" did not exist; In analysis_template.R, line 85, the function "importance" did not exist, either.
I wonder if these functions were contained in the packages and were replaced by other expressions in the new versions, or I have simply got something wrong.

Issue partly solved.
The function "importance" needs the package "random forest", which was not contained in the original code.
