R programming tutorial: Using ggplot2 for dot plots in R

Dot plots provide a method of plotting a large number of labeled values on a simple horizontal scale. A dot plot or dot chart is similar to a scatter plot. The main difference is that the dot plot in R displays the index (each category) in the vertical axis and the corresponding value in the horizontal axis, so you can see the value of each observation following a horizontal line from the label. To produce a dot plot in R, you can use dotchart() function; To pruduce a dot plot using ggplot2 package, you can use geom_point() #rprogramming #rstudio #ggplot #dotplot #rdatacode
