I would create a tar.gz file from R. But the tar function doesn't work me. This is my example code.
我会从R创建一个tar.gz文件但是tar函数对我不起作用。这是我的示例代码。
writeLines('aaaa', 'tmp.txt')
tar('tmp.tar.gz', 'tmp.txt', compression = 'gzip')
This code creates a tmp.tar.gz, but tmp.txt doesn't include in the gz file.
此代码创建tmp.tar.gz,但tmp.txt不包含在gz文件中。
Are there any mistakes in my code?
我的代码中有错误吗?
Thanks for any suggestions.

I guess you do not have set the "tar" environmental variable. The default argument of tar() called tar is set by a call to Sys.getenv("tar"). If it is an empty string, then R's internal tar is used (it doesn't work on my system either).
我猜你没有设置“tar”环境变量。调用tar的tar()的默认参数是通过调用Sys.getenv(“tar”)来设置的。如果它是一个空字符串,则使用R的内部tar(它在我的系统上也不起作用)。
So, you may either Sys.setenv the "tar" variable, or provide the name of external tar command/path manually:
因此,您可以使用Sys.setenv“tar”变量,也可以手动提供外部tar命令/路径的名称:
tar('tmp.tar.gz', 'tmp.txt', compression = 'gzip', tar="tar")
