r - 无法抑制 blogdown/knitr 中的消息

Question

这是 blog使用 blogdown 创建的帖子

R 代码块以

```{r, echo = FALSE, message = FALSE, warning = FALSE}

但是，每次我使用 sf::st_read 读取 shapefile 时，都会出现三条消息。

如何防止这些消息出现在帖子中？

答案是否在 this关于 knitr 选项的页面？

Answer 1

将最初发布在评论中的明显解决方案移至完整答案。推理概述 in this meta discussion

I think st_read is just printing output normally, this won't be affected by message = FALSE or warning = FALSE. If you don't need any output from the chunk you can do results = 'hide' in the chunk options, otherwise I think you can stop it printing using st_read(..., quiet = TRUE)
