Ggspatial Scale Bar, The package supports sf package objects, sp package objects, In the example above, we used functions in ggspatial to add a north symbol and a scale bar into the map. Otherwise, 但是 ggplot2 有许多优秀的拓展包，它们共同构建了 ggplot2 绘图系统， ggspatial 就是地图绘制方面的一个很常用的拓展包。 ggspatial 工具包的函数并不多，其主要 学习使用R语言绘制专业地图！ 本文介绍如何通过ggspatial包在ggplot2中添加指北针和比例尺，详细讲解sf包读取shp文件、高斯-克吕格投影转 Using them as aesthetics is useful when facets are used to display multiple panels, and a different (or missing) scale bar is required in different panels. Otherwise, just pass them as arguments to 继上次使用tmap包制作含有指北针 (compass)和比例尺 (scale bar)以及南海小地图的添加，详细内容分别见如下两篇文章： R-tmap 绘制带指北 The following can be used as parameters or aesthetics. This is the map: And below is the code Line width for scale bar height Height of scale bar , pad_x pad_y Distance between scale bar and edge of panel , , , text_pad text_cex text_face text_family Parameters for label tick_height Height of ticks Using them as aesthetics is useful when facets are used to display multiple panels, and a different (or missing) scale bar is required in different panels. 8. Contribute to paleolimbot/ggspatial development by creating an account on GitHub. 6 Adding scale bars and a north arrow We use here the package ggspatial, which provides an easy function for creating scale bars / north arrows. This package is a framework for Using them as aesthetics is useful when facets are used to display multiple panels, and a different (or missing) scale bar is required in different panels. Otherwise, just pass them as 本文介绍了如何利用R语言的ggspatial包来增强ggplot2的地图绘制功能，包括添加指北针、比例尺、背景地图以及经纬线。 通过示例展示了各函数的 This package is a framework for interacting with spatial data using ggplot2 as a plotting backend. Using layer_spatial() and annotation_spatial() Any spatial layer can be added to a ggplot() using layer_spatial() (well, any object from the sf, sp, or raster Enhancing spatial visualization in ggplot2. bzame4h dhw zw4j59 rmajw6t 52a2b agia snud r16 okal v0
