Here is some quick advice on how to get up and running with R + r Java on Windows 7 64bit. There are several possibilities, but most have fatal flaws. Here is what worked for me: Add jvm.dll to your PATH r Java, the R<-> Java bridge, will need jvm.dll, but R will have trouble finding that DLL. It resides in a folder like C:\ Program Files\ Java\jdk _25\jre\bin\server C:\ Program Files\ Java\jre6\jre\bin\client Wherever yours is, add that directory to your windows PATH variable. ( Windows -> Path -> Edit environment variables to for your account -> PATH -> edit the value.) You may already have Java on your PATH. If so you should find the client/server directory in the same Java home dir as the one already on your PATH. To be safe, make sure your architectures match. If you have Java in Program Files, it is 64-bit, so you ought to run R64. If you have Java in Program Files (x86 that's 32-bit, so you use plain 32-bit R. Re-launch R from the Windows Menu If R is running, quit. From the Start Menu, Start R / RGUI, RStudio. This is very important, to make R pick up your PATH changes. Install r Java. Earlier versions do not work! Mirrors are not up-to-date, so go to the source at : Note the advice there “ Please use `install.packages r Java to install.” That is almost correct. This actually works: install.packages r Java'.lib Paths [1], ' Watch the punctuation! The mysterious “.lib Paths [1],” just tells R to install the package in the primary library directory. For some reason, leaving the value blank doesn’t work, even though it should default.
