What this article shares with you is about the R language version of the data map. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.

What I want to share with you today is the R language version of the data map, provincial (municipal) thermal map.

The steps are basically the same as the steps of the thermal map of China shared yesterday, except that the data files that need to be called and the index files that need to be customized are slightly different.

R language system environment configuration:

R version 3.2.3

RStudio Version 0.99.484

Before you begin, you must make sure that the following packages are installed in your R language environment:

Ggplot2

Plyr

Maptools

If you haven't already installed, you need to install install.packages ("ggplot2", "plyr", "maptools") first.

Here are the formal drawing steps:

1. Load the required R package:

Library (ggplot2)

Library (plyr)

Library (maptools)

2. Read in the drawing data:

CHN_adm2
