Hi
I'm trying to get to grips with R and establish R as a teaching medium in my secondary school. I would like to use R to analyse text so I can produce frequency analysis of the text for subsequent examination of ciphers. I can produce code in VBA but I am struggling when writing in R to examine each character. There must be a clear method using the vectorised format of R. Furthermore, how do you substr a text string and reference each letter? I can use nchar to see how many letters per string but not to select each letter. I would prefer to remain in R and not deviate to Python etc as getting R onto the school mainframe has been a long journey...
Many thanks
