For creating a barplot in R you can use the base R barplot function. This post was an overview of ggplot2 barplots, showing the basic options of geom_barplot(). Any feedback is highly encouraged. We should have two sets, âchickensâ and âeggsâ. We can fix the order of this category by changing the factor. One of the reasons you’d see a bar plot made with ggplot2 with no ascending / descending order - ordering / arranged is because, By default, ggplot arranges bars in a bar plot alphabetically.. #customizing barplot-changing theme ggplot (df, … Grouped Barplot in R; Stacked Barplot in R; Order Bars of ggplot2 Barchart in R; R Graphics Gallery; R Functions List (+ Examples) The R Programming Language . Weâll adjust the x-axis label (xlab), y-axis label (ylab), title (ggtitle) and update the look using theme_bw().
