The other method is to change the X and Y axis limits by zooming in to the region of interest without deleting the points. This feature might come in handy when you wish to know how the line of best fit would change when some extreme values (or outliers) are removed. Using ggplot, you can add more layers, themes and other settings on top of this plot.ĭid you notice that the line of best fit became more horizontal compared to the original plot? This is because, when using xlim() and ylim(), the points outside the specified range are deleted and will not be considered while drawing the line of best fit (using geom_smooth(method='lm')). This is because, the previous plot was stored as g, a ggplot object, which when called will reproduce the original plot. In this case, the chart was not built from scratch but rather was built on top of g. G <- ggplot(midwest, aes( x=area, y=poptotal)) + geom_point() + geom_smooth( method= "lm") # set se=FALSE to turnoff confidence bands # Delete the points outside the limits Let’s initialize a basic ggplot based on the midwest dataset. The second noticeable feature is that you can keep enhancing the plot by adding more layers (and themes) to an existing plot created using the ggplot() function. All the data needed to make the plot is typically be contained within the dataframe supplied to the ggplot() itself or can be supplied to respective geoms. The main difference is that, unlike base graphics, ggplot works with dataframes and not individual vectors. The syntax for constructing ggplots could be puzzling if you are a beginner or work primarily with base graphics.

Part 3: Top 50 Ggplot2 Visualizations - The Master List, applies what was learnt in part 1 and 2 to construct other types of ggplots such as bar charts, boxplots etc. Part 2: Customizing the Look and Feel, is about more advanced customization like manipulating legend, annotations, multiplots with faceting and custom layouts Part 1: Introduction to ggplot2, covers the basic knowledge about constructing simple ggplots and modifying the components and aesthetics. This tutorial is primarily geared towards those having some basic knowledge of the R programming language and want to make complex and nice looking charts with R ggplot2. This is part 1 of a three part tutorial on ggplot2, an aesthetically pleasing (and very popular) graphics framework in R. So, for practical purposes I hope this tutorial serves well as a bookmark reference that will be useful for your day-to-day plotmaking.

It goes into the principles, steps and nuances of making the plots effective and more visually appealing. I start from scratch and discuss how to construct and customize almost any ggplot.

Now, this is a complete and full fledged tutorial. It quickly touched upon the various aspects of making ggplot. Previously we saw a brief tutorial of making charts with ggplot2 package. The Complete ggplot2 Tutorial - Part1 | Introduction To ggplot2 (Full R code)
