ggplot(data = Book1, aes(x = Rental Price (per sq metre))) + geom_histogram(binwidth = 5), fill = "green", colour = "green", alpha = 0.5) + ggtitle("Histogram of Rental Price") + ylab("Counts")
Error: unexpected symbol in "ggplot(data = Book1, aes(x = Rental Price"
Does anyone know what the error is and how to fix it?
