I used the procedure at the following website: https://github.com/MTFA/CohortEx/wiki/Run-rJava-with-RStudio-under-OSX-10.10,-10.11-(El-Capitan)-or-10.12-(Sierra)

The main steps are:

1. Install Apple Java 6
2. Install the newest Java from Oracle
3. Fix JAVA_HOME to point to the new version. Terminal command: sudo R CMD javareconf
4. Install rJava from source. Terminal command: unset JAVA_HOME; R --quiet -e 'install.packages("rJava", type="source", repos="http://cran.us.r-project.org")'

My environment is

java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

R version 3.4.3 (2017-11-30) -- "Kite-Eating Tree"
Copyright (C) 2017 The R Foundation for Statistical Computing
Platform: x86_64-apple-darwin15.6.0 (64-bit)

macOS High Sierra 10.13.2

I encountered this problem today and spent whole day trying to fix it. Luckily I found the solution at last. It works for me.

sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib

Note:

If the get ln: /usr/local/lib/libjvm.dylib: File exists in terminal. Then you should delete this file and run the command above again.

@Kayle Sawyer's answer works almost perfectly, but you might need to reinstall command line tools first. Easiest way is to run the following in Terminal:

xcode-select --install

If you get an error saying command line tools are already installed, you can reinstall the package with this:

cd /Library/Developer/CommandLineTools/Packages/
open macOS_SDK_headers_for_macOS_10.14.pkg

You might need to update the second command based on your OS version.
