Making Maps with GGPLOT. In the previous lesson, you used base plot() to create a map of vector data - your roads data - in R.In this lesson you will create the same maps, however instead you will use ggplot().ggplot is a powerful tool for making custom maps. Compared to base plot, you will find creating custom legends to be simpler and cleaner, and creating nicely formatted themed maps to be.
This article describes how to add and change a main title, a subtitle and a caption to a graph generated using the ggplot2 R package.

Spot Matrix in R with ggplot2 The spot matrix is a visualization of a table of numbers. It’s used when when you have two discrete axes, and at each intersection there is an ordinal value to be displayed.
Creating a risk matrix graphic using R and ggplot2. In this post we’re going to look at creating a risk matrix using R and ggplot2 to visualise the time impact, probability, and cost of various tasks. The finished product will look like this: Let’s start with our imports, for this post we’ll need ggplot2 and scales: In (1): library (ggplot2) library (scales) Let’s bring in our dataset.
The R ggplot2 boxplot is useful for graphically visualizing the numeric data group by specific data. Let us see how to Create an R ggplot2 boxplot, Format the colors, changing labels, drawing horizontal boxplots, and plot multiple boxplots using R ggplot2 with an example.

The first step is to get the boundaries of the zone that interests you. Several option are available in R, as extensively described in the background map section of the gallery. Briefly, you can find this information somewhere under the shapefile format or under the geoJSON format. You can also load google like backgrounds with the ggmap library. This post uses the last approach: it loads.
Produce scatter plots, boxplots, and time series plots using ggplot. Set universal plot settings. Describe what faceting is and apply faceting in ggplot. Modify the aesthetics of an existing ggplot plot (including axis labels and color). Build complex and customized plots from data in a data frame. We start by loading the required packages. ggplot2 is included in the tidyverse package. library.
