many thanks for your responses which have helped me to proceed.
Sometimes doing your homework before asking can appear quite obvious but
to newbies it is also quite difficult to get the correct question;
therefore I appreciate your valued responses.
Happy New Year to you all
Bob

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
