在SUSElinux服务器上安装R包- FSELCETOR

Question

我有一个帐户到Suse linux服务器，没有根访问。我已经安装了一个R，现在我想使用FSELECTOR软件包。我从以下步骤开始：

$ whereis java
java: /usr/bin/java /usr/lib64/java /etc/java /usr/share/java /usr/share/man/man1/java.1.gz
$ R CMD javareconf -e
$unset JAVA_HOME

然后我开始了R

Sys.setenv(JAVA_HOME='\\usr\\lib64\\java\\)
install.packages("FSelector")

在安装过程中，我收到了以下消息：

Error: package or namespace load failed for ‘rJava’:
 .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/home/korosig/R/x86_64-suse-linux-gnu-library/3.5/rJava/libs/rJava.so':

有а吗？

我想安装rJava，但是我得到了同样的结果。

Sys.setenv(JAVA_HOME='\\usr\\lib64\\jvm\\java-10-openjdk-10')
install.packages("rJava")
Installing package into ‘/home/korosig/R/x86_64-suse-linux-gnu-library/3.5’
