[英]Can't suppress messages in blogdown/knitr
Here is a blog post created with blogdown 这是一篇用blogdown创建的博客文章
The R chunk of code begins with R代码块以。开头
```{r, echo = FALSE, message = FALSE, warning = FALSE}
However, three messages appear each time I read a shapefile using sf::st_read
但是,每次使用sf::st_read
读取shapefile时都会出现三条消息
How do I prevent these messages from appearing in the post? 如何防止这些消息出现在帖子中?
Does the answer lie in this page about knitr options? 关于knitr选项的答案在于这个答案吗?
Moving an apparent solution initially posted in the comments to a full answer. 将最初在评论中发布的明显解决方案移至完整答案。 Reasoning outlined in this meta discussion 在这个元讨论中概述了推理
I think
st_read
is just printing output normally, this won't be affected bymessage = FALSE
orwarning = FALSE
. 我认为st_read
只是正常打印输出,这不会受到message = FALSE
或warning = FALSE
。 If you don't need any output from the chunk you can doresults = 'hide'
in the chunk options, otherwise I think you can stop it printing usingst_read(..., quiet = TRUE)
如果您不需要块中的任何输出,您可以在块选项中执行results = 'hide'
,否则我认为您可以使用st_read(..., quiet = TRUE)
停止打印
