  Error: Unable to load shared target 'C:/Program Files/R/R-3.1.3/library/rJava/libs/i386/rJava.dll'::
  LoadLibrary failure: %1 Not a valid Win32 application.

Error: 'rJava' programming package or namespace failed to load.

RJava loading error: The R client USES Windows 32bit, the operating system version is 64bit, and the system installed Java is 64bit, which is not compatible with rJava.

C:\Users\asus>java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) **64-Bit** Server VM (build 25.45-b02, mixed mode)

The solution, using a 32-bit JRE, is to reset the environment variable.

> Sys.setenv(JAVA_HOME='C:\\Program Files (x86)\\Java\\jre6')
> library('rJava')

Resetting the environment variables before loading rJava, OK
