- Possible solution:
use `strrep(' ', c(1,3,6,0))` instead.

- Chinese summary 简中梗概：

由于`v_spaces`函数已被废弃，章节 6.4.2 向源代码中添加行号 编译失败。通过查 knitr 源码[变更](https://github.com/yihui/knitr/commit/c98b1548b1ceb30d3f84aa908494f20126003649#diff-8ad583a41c5b62767d4a6deaf61d81980705cbb60852f7280c7de9e939c8b532R493-R494) 可知，使用`strrep`函数是knitr作者的选择。`strrep(' ', c(1,3,6,0))`的编译结果与原文效果一致。
