Your PROFILE FILE does not exist. This problem must be fixed to continue.
The code expects the file "./myScripts/.myProfile.R" to exist and to

Try running init() again and follow the instructions. Reload youR RStudio

Your STUDENT NUMBER has not been defined. This problem must be fixed to continue.
The code expects the file "./myScripts/.myProfile.R" to exist and to
contain your correct eMail address and student number. This file gets
sourced when you start a new R-session, but since you see this error
message there was a problem.
Perhaps you need to restart your R-session. Try closing the RStudio
project and reopening it from the File > Recent Projects menu.
Perhaps there was a syntax error in your file. Then not all the
instructions in the file are executed. Check the file: is your
email perhpas not defined? Or did you type it without qwuoataion
marks?
Try fixing problems, and then restart R as described above.
If none of this fixes the problem, ask for help.
