Question

我在我的Linux系统中安装了R。我还安装了一个包“x”。我想编写一个简单的shell脚本来检查该库是否正确加载。还可以说，在'x'包中有一个名为'f'的API，我的shell脚本应该能够运行它并验证它是否正常工作而没有任何错误。

简而言之，我想借助shell脚本测试下面的R功能。如果下面的东西工作返回true其他错误

$ R

Type 'q()' to quit R.

R > library(x)
 library loaded
R> f(c(1,2,3))
 #No error thrown

Answer 1

应该像这样工作：

R --no-save <<EOF
library(x)
f(c(1,2,3))
EOF
if test $? = 0 ; then
  echo "good"
else
  echo "bad"
fi

使用shell脚本测试R库加载功能
