Advanced ggplot2: Barplot with highlights : Plot the plots as we see in research Journals

#rprogramming #barcharts #barplot #ggplot2

This tutorial series will help you to make plots which are at par with what we see in research journals.

In this video I have discussed:

1. How to get highlighted bars in barplot
2. customise the plot using theme elements
3. use scale_continuous to customise tick labels and plot origin
4. Add greek letters and superscripts in axis labels
5. Get text on the plot using annotate layers
6. Customise text elements using theme elements.

The original plot is from

I guessed the data from the plot and recreated it in this tutorial.

Sir I am not able to get my exel file or data file in R studio.. I am trying to get plots for insect diversity from different sites...
Please highlight this issue or make any video on insect diversity related please...
