无法载入共享目标对象‘...rJava.dll’

1、问题

在安装RWordReg包时出现如下错误：

> utils:::menuInstallPkgs()
installing the source package ‘Rwordseg’

试开URL’http://R-Forge.R-project.org/src/contrib/Rwordseg_0.2-1.tar.gz'
Content type 'application/x-gzip' length 5445754 bytes (5.2 MB)

下载的程序包在

2、解决

在R语言环境中设置JRE路径：

> Sys.setenv(JAVA_HOME='D:/jdk1.6.0_45/jre')

注意是JRE路径，而不是JDK的路径。
