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 [[alternative HTML version deleted]]
