Hello. I am a student in social science at the University of Lausanne.

I have a problem to solve with R. I'm desperately looking for someone who is
able to solve it.

The problem is the following:
I need to decode a message using a substitution encryption.
First, I must create the encryption in R (in the R language). Then, I should
write a function in R, wich is able to give the key and the decoded message. We
can use any encryption, for example a simple substitution.



Unfortunately I have many difficulties in using this software. I would be
very grateful if you help me.

Thank you very much. Waiting for your answers



Andrea
