hello! i am working with a given line of code for a beginner's course, which says:
qplot(BOD$Time, BOD$demand, geom = "bar", stat = "identity"
but it isn't working ("identity" is a y aesthetic) , so I've been playing around with different versions including my latest one:
qplot(BOD$Time, BOD$DEMAND, aes(geom_bar(stat = "identity")))
but here, the aesthetic is the wrong length. How do I use stat and geom correctly?
