R-Markdown避免加载包消息 [英] R - Markdown avoiding package loading messages

问题描述

我一直通过R-Studio使用Knitr，并且认为它非常简洁.我有一个小问题.当我在R-Chunk中获取文件时，knitr输出包括如下外部注释:

I have been using Knitr via R-Studio, and think it is pretty neat. I have a minor issue though. When I source a file in an R-Chunk, the knitr output includes external comments as follows:

+ FALSE Loading required package: ggplot2
+ FALSE Loading required package: gridExtra
+ FALSE Loading required package: grid
+ FALSE Loading required package: VGAM
+ FALSE Loading required package: splines
+ FALSE Loading required package: stats4
+ FALSE Attaching package: 'VGAM'
+ FALSE The following object(s) are masked from 'package:stats4':

我试图以各种方式设置R-chunk选项，但似乎仍无法避免该问题:

I have tried to set R-chunk options in various ways but still didn't seem to avoid the problem:

```{r echo=FALSE, cache=FALSE, results=FALSE, warning=FALSE, comment=FALSE, warning=FALSE} 
source("C:/Rscripts/source.R");

```

有什么办法可以注释掉这些消息?

Is there any way to comment out these messages?

推荐答案

您可以使用include=FALSE排除块中的所有内容.

You can use include=FALSE to exclude everything in a chunk.

```{r include=FALSE}
source("C:/Rscripts/source.R")
```

如果只想禁止显示消息，请改用message=FALSE:

If you only want to suppress messages, use message=FALSE instead:

```{r message=FALSE}
source("C:/Rscripts/source.R")
```
