This article describes how to create a barplot using the ggplot2 R package.
One axis of the chart shows the specific categories being compared and the other axis represents a discrete value scale. Despite being widely cited, these graphical data are difficult to implement because there are no accompanying numerical values for the parameters underlying the growth data. Barplot (also known as Bar Graph or Column Graph) is used to show discrete, numerical comparisons across categories. These findings were presented graphically to assess the rate of tooth formation in living children and to age immature skeletal remains. (Am J Phys Anthropol 21 (1963) 99-108 J Dent Res 42 (1963) 1490-1502) presented the “mean attainment age” for stages of tooth development for 10 permanent tooth types and three deciduous tooth types. In two historic longitudinal growth studies, Moorrees et al.
