I have a dataset with a variable that is non-numeric. I was wondering if there is an easy way in R to create a bar graph that will tell me how many of each level of this non-numeric variable are in the overall dataset. Specifically, if my variable is LETTER, and I have A, B,C, D, E, F and I want to find out how many of each letter there are, what is the easiest way to do this in R and use the information to make a plot? jdr
