#Q1 Matrix that contains A-Z letters in columns with coordinates corresponding
#   with code using numbers:
#   For example; A loc in row 1 and col 2, so the code for 'A' becomes '12'

#   The data is held in a file called cipher.csv
#   This is within the R Scripts folder of the current working directory 
#   and contains headers

#   Load file

results<-read.csv("R Scripts/cipher.csv",header=FALSE, stringsAsFactors = TRUE)
#   to show column classes as character

#   to print results

results1<-results[-1,-1]
#   make NEW chart minus row 1 and column 1 to match example given

#   renames rows
#    new chart with column and row values that exactly correspond with example

 
dim(results1) # to check the dimensions of results 1 (4 rows 10 columns)
