这里的问题并不完全是如何通过R绘制地图,因为我已经发现这里有一个非常好的例子,而是如何让它工作.实际上,我无法加载库rgdal:

library(rgdal)
Error in library(rgdal) : there is no package called ‘rgdal’

但是,当我尝试手动安装上面的包时,我收到以下错误:

....
configure: error: proj_api.h not found in standard or given locations.
ERROR: configuration failed for package ‘rgdal’
* removing ‘/home/eualin/R/i686-pc-linux-gnu-library/2.15/rgdal’
Warning in install.packages : installation of package ‘/home/eualin/Downloads/rgdal_0.8-5.tar.gz’ had non-zero exit status

欢迎任何投入!

当我在将R从3.4.4更新到3.5.1之后通过从源代码编译来更新(或至少尝试)rgdal包时,我遇到一个奇怪的问题,一切顺利,但命名空间加载由于"未定义的符号"错误:

在跑步的时候,echo _ZNK10OGRFeature16GetFieldAsDoubleEi | c++filt我得到的输出OGRFeature::GetFieldAsDouble(int) const并没有让我学到很多东西.我已经安装了GDAL从 …

我的Ubuntu机器有最新的GDAL(2.2.1,2017/06/23发布).但是R抱怨说我的gdalversion <2.0

configure:CC:gcc -std = gnu99 configure:CXX:g ++检查gdal-config .../usr/bin/gdal-config检查gdal-config usability ... yes configure:GDAL:1.11.3检查GDAL版本> = 2.0.0 ...无配置:错误:sf与2.0.0以下的GDAL版本不兼容

如何指示R访问已安装在Ubuntu上的GDAL(2.2.1版本)？

系统信息:

Ubuntu 16.04

我正在尝试为研究项目安装rgdal_1.2-16.tar.gz.我看着这里,做

sudo apt-get install libgdal1i

R CMD INSTALL rgdal_1.2-16.tar.gz

* installing *source* package ‘rgdal’ ...

那么我试着打开R:
