Creare the grouped bar plots: Key function: geom_bar (). A basic scatter plot has a set of points plotted at the intersection of their values along X and Y axes. ‘concerned’ and ‘not concerned’), dot plots are a superior way to visualize your data. The subgroups are just displayed on top of each other, not beside. (The code for the summarySE function must be entered before it is called here). It’s different from the Cleveland dot plots shown in Recipe 3.10.In these Wilkinson dot plots, the placement of the bins depends on the data, and the width of each dot corresponds to the maximum width of each bin. Graphs are the third part of the process of data analysis. Syntax of dotchart () function in R for Dot plot: dotchart (NumericVector, cex = 1, col = “black”, labels = … it's printed to the upper right corner.
