摘要
随着不同学科的交叉融合发展,基于地理信息系统(GIS)的绘图在经济学中发挥着越来越重要的作用。而具有强大可视化绘图功能的R语言,通过编写新代码或调整已有代码可轻松实现科研中数据呈现与图形绘制的要求。文章以贵州省2017年9个地级行政区的GDP增长率为例,使用3.5.1版本的R语言、R编辑器RStudio并载入相关的R-package绘制出有指北针、比例尺、不同类型图例的地图并提供相应的脚本与说明,为经济学研究中直观地表述研究结果提供了良好的范例,以方便从事经济学研究的人员直接更改使用。
With the development of interdisciplinary integration,mapping based on Geographic Information System(GIS)plays an increasingly important role in economics.R language,which has powerful visual drawing function,can easily meet the requirements of data presentation and graphics drawing in scientific research by writing new codes or adjusting existing codes.Taking the GDP growth rate of nine prefecture-level administrative regions in Guizhou Province in 2017 as an example,this paper draws maps of different types of legends and provides corresponding scripts and explanations by using R language of version 3.5.1,RStudio editor and loading relevant R-package,which provides an intuitive description of the research results in economic research.Thus,people engaged in economic research can implement direct use from this example.
