$ brew tap homebrew/science $ brew install R ==> Installing homebrew/science/r dependency: readline ==> Caveats This formula is keg-only, which means it was not symlinked into /usr/local, because macOS provides the BSD libedit library, which shadows libreadline. In order to prevent conflicts when programs look for libreadline we are defaulting this GNU Readline installation to keg-only.. For compilers to find this software you may need to set: LDFLAGS: -L/usr/local/opt/readline/lib CPPFLAGS: -I/usr/local/opt/readline/include ==> Installing homebrew/science/r dependency: gettext ==> Caveats This formula is keg-only, which means it was not symlinked into /usr/local, because macOS provides the BSD gettext library & some software gets confused if both are in the library path. If you need to have this software first in your PATH run: echo 'export PATH="/usr/local/opt/gettext/bin:$PATH"' >> ~/.bash_profile For compilers to find this software you may need to set: LDFLAGS: -L/usr/local/opt/gettext/lib CPPFLAGS: -I/usr/local/opt/gettext/include ==> Installing homebrew/science/r ==> Caveats To enable rJava support, run the following command: R CMD javareconf JAVA_CPPFLAGS=-I/System/Library/Frameworks/JavaVM.framework/Headers If you've installed a version of Java other than the default, you might need to instead use: R CMD javareconf JAVA_CPPFLAGS="-I/System/Library/Frameworks/JavaVM.framework/Headers -I/Library/Java/JavaVirtualMachines/jdk<version>.jdk/" (where <version> can be found by running `java -version`, `/usr/libexec/java_home`, or `locate jni.h`), or: R CMD javareconf JAVA_CPPFLAGS="-I/System/Library/Frameworks/JavaVM.framework/Headers -I$(/usr/libexec/java_home | grep -o '.*jdk')"
