I have data with columns for animal ID, breed, and weight. I'd like to create a box plot of weight, separated by breed (there are 4 breeds).
Any ideas?
1. Did you check the help page: ?boxplot
Here's a sample of the data (there are 100 rows): id weight breed 1 453 brahman 2 527 brahman 3 520 brahman 4 460 brahman 5 496 brahman 6 461 brahman 7 519 brahman 8 472 brahman 9 531 brahman 10 473 brahman 11 509 brahman 12 503 brahman
B. Perhaps something like this? boxplot(weight ~ breed) Look at the use of a formula when plotting. If I misread your intent I apologize.
