我最近升级到了 Ubuntu 22.04。升级后，R 控制台似乎无法正常工作。问题是，当我将几行代码粘贴到 R 控制台时，只有几行代码被附加（似乎是对要粘贴的行数的限制）。例如，尝试将以下内容粘贴到 R 控制台中，只有几个条目（最多 158 行被正确附加）。我用其他 R 版本（4.1.2；4-2.0；4-2.1）测试了这一点，所有版本都存在此问题。Ubuntu 20 下不存在此问题。任何帮助都将不胜感激。

答案1
这可能是您使用的终端仿真器的一个限制。不过，最好不要复制粘贴大段代码。相反，请使用source()，并将复制/粘贴留给您可以监督的较小、可管理的文本片段。
或者，您也可以关闭“括号粘贴”恢复到终端的传统行为，其中粘贴的行将逐行执行。
