Build the R language environment in Linux and build the linuxr Language

R is the language and operating environment used for statistical analysis and drawing. R is a free, free, and open source software in the GNU system. It is an excellent tool for Statistical Computing and statistical drawing.

Environment setup:

1. Install proj

[root@uvmsvr12 gis]#wget http://download.osgeo.org/proj/proj-4.9.1.tar.gz[root@uvmsvr12 gis]# tar -zxvf proj-4.9.1.tar.gz[root@uvmsvr12 proj-4.9.1]# cd proj-4.9.1[root@uvmsvr12 proj-4.9.1]# ./configure[root@uvmsvr12 proj-4.9.1]# make && make install

After the installation is complete, the. h file (org_proj4_Projections.h, proj_api.h, projects. h) is generated under/usr/local/lib, and the library file is generated under the/usr/lib folder.

Add/usr/local/lib to the environment variable:

[root@uvmsvr12 proj-4.9.1]# vim /etc//ld.so.conf.d/local.conf/usr/local/lib[root@uvmsvr12 proj-4.9.1]#ldconfig -v

2. Install GEOS

[root@uvmsvr12 gis]# wget http://download.osgeo.org/geos/geos-3.4.2.tar.bz2[root@uvmsvr12 gis]# tar -jxvf geos-3.4.2.tar.bz2[root@uvmsvr12 gis]# cd geos-3.4.2[root@uvmsvr12 gis]# make && make install

3. Install gdal

[root@uvmsvr12 gis]#wget http://download.osgeo.org/gdal/CURRENT/gdal-1.11.2.tar.gz[root@uvmsvr12 gis]# tar -zxvf gdal-1.11.2.tar.gz[root@uvmsvr12 gis]# cd gdal-1.11.2[root@uvmsvr12 gis]# ./configure --with-geos=/usr/local/bin/geos-config[root@uvmsvr12 gis]# make && make install

Note:

In. /configure check configuration information displays whether the related components are supported. If "GEOS support: no" is displayed, geos is not supported, we need to add the parameter -- with-geos =/usr/local/bin/geos-config.

4. Install the R Language

(1) first install the java environment, such:

##JAVA###export JAVA_HOME=/usr/local/jdkXXXexport JRE_HOME=/usr/local/jdkXXX/jreexport PATH=$JAVA_HOME/bin:$PATHexport CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

Do not forget source/etc/profile to load environment variables.

(2) install the R Language

[root@uvmsvr12 gis]# yum install gcc-gfortran readline-devel libXt-devel[root@uvmsvr12 gis]# wget http://mirror.bjtu.edu.cn/cran/src/base/R-3/R-3.2.0.tar.gz[root@uvmsvr12 gis]# tar -zxvf R-3.2.0.tar.gz[root@uvmsvr12 gis]# cd R-3.2.0[root@uvmsvr12 gis]# ./configure  --enable-R-shlib  --prefix=/usr/local/R-3.2.0[root@uvmsvr12 gis]# make && make install

Note:

If the error"Configure: error: No F77 compiler found", Yum install gcc-gfortran is required.

If"Configure: error: -- with-readline = yes (default) and headers/libs are not available, configure: error:-with-x = yes (default) and X11 headers/libs are not available", Yum install readline-devel libXt-devel is required.

If you cannot use the R environment tab auto-completion or the up and down arrow keys, you also need to install yum install readline-devel libXt-devel.

Finally, add the execution command of your R language to the environment variable, so that you can directly enter by entering R.

Export PATH =/usr/local/The R-3.2.0/bin: $ PATH

In addition, use the R installation package

Check whether require (rjson) is installed in the package)

If"Geos-config not found" or "gdal-config not found"While our geos-config and gdal-config have been installed under/usr/local/bin. We need to add/usr/local/bin to the environment variable.
