So I found the duplicates and changed them, however I get a new error:
Quitting from lines 43-43 (Calibration_assignment.Rmd)
Error in setwd(dir) : cannot change working directory
Calls: ... process_group.inline -> call_inline -> in_dir -> setwd
Execution halted
I went to line 43 and I am not sure what is wrong about it. I didn't the original code as it was given to us by a professor we just had to change to to fit our data
