Barplot(also known as Bar Graph or Column Graph) is used to show discrete, numerical comparisons across categories. One axis of the chart shows the specific categories being compared and the other axis represents a discrete value scale.
# Bar graph, time on x-axis, color fill grouped by sex -- use position_dodge() ggplot(data=dat1, aes(x=sex, y=total_bill, fill=time)) + geom_bar(stat="identity", position=position_dodge(), colour="black") See ../Colors (ggplot2) for more information on colors....
