Hi, I am a complete R rookie so this question is probably really simple but I haven't found an answer on the web that I can understand.
My data frame has 3 columns, A, B and C. A and B have numbers (about 8000 rows), C is a factor which is either true or false. So I can plot A vs B with plot(dataframe$A, dataframe$B). However, I would like the points to be different colors depending on whether C is True or False. Even better, if C had more than 2 groups, like group 1,2,3 can I make all 3 different colors, etc? It would be really helpful to give an example using my scenario since I have a lot of trouble understanding other examples on the web because the data is not set up like my data. Thanks so much!!!
