我正在尝试安装在Ubuntu Linux 12.04上运行的R 2.14.1的RWeka软件包。 我input：
install.packages("RWeka") select一个镜像，并下载。
然后我得到这些消息：
configure: error: Java Development Kit (JDK) is missing or not registered in R Make sure R is configured with full Java support (including JDK). Run R CMD javareconf as root to add Java support to R. If you don't have root privileges, run R CMD javareconf -e to set all Java-related variables and then install rJava. ERROR: configuration failed for package 'rJava' * removing '/home/~/R/x86_64-pc-linux-gnu-library/2.14/rJava' ERROR: dependency 'rJava' is not available for package 'RWekajars' * removing '/home/~/R/x86_64-pc-linux-gnu-library/2.14/RWekajars' ERROR: dependencies 'RWekajars', 'rJava' are not available for package 'RWeka' * removing '/home/~/R/x86_64-pc-linux-gnu-library/2.14/RWeka' The downloaded packages are in '/tmp/RtmpZBJDM0/downloaded_packages' Warning messages: 1: In install.packages("RWeka") : installation of package 'rJava' had non-zero exit status 2: In install.packages("RWeka") : installation of package 'RWekajars' had non-zero exit status 3: In install.packages("RWeka") : installation of package 'RWeka' had non-zero exit status
所以我退出并input：
sudo apt-get install icedtea-7-plugin
让它运行，然后：

然后我回去开始R并inputinstall.packages（“RWeka”）
并像以前一样得到相同的错误信息。
有什么build议么？
看起来您可能安装了JRE（Java运行时环境），但是没有安装JDK（Java开发工具包）。
尝试：
sudo apt-get install openjdk-6-jdk
然后尝试再次安装该软件包。
