回送长字符串时R系统命令出错

尝试在R中使用system（）命令写入特定的输入字符串。但是，如果命令未完成，则使用+符号失败

但是随机删除某个部分，就可以运行它了

这不是因为长度问题，因为我看到它处理较长的文本。

您是否尝试过

system2

？请注意，调用是不同的。它必须是一个没有参数的命令，在另一个参数中传递。@RuiBarradas对此有何更改。你能帮忙吗？你必须把

echo

的参数放在字符串向量中。如果命令行很长，请将其打断：

system2（“echo”，args=c（“$PATH”，“$R\u HOME”）

。这没有帮助。我所做的不是一次写入整个字符串，而是在循环中写入。
