抑制包加载消息

Question

我用谷歌搜索了一下，发现如果我使用，suppressPackageStartupMessages()我应该能够解决我的问题，但事实证明，什么也没发生。

我正在像这样加载我的包裹：

if (!require("gplots", quietly = T)) {
    sink("/dev/null")
    suppressPackageStartupMessages(suppressWarnings(suppressMessages(install.packages("gplots"))))
    suppressPackageStartupMessages(suppressWarnings(suppressMessages(library("gplots", quietly = T))))
}

当我的脚本运行时，我收到以下消息：

Attaching package: ‘gplots’

The following object is masked from ‘package:IRanges’:

    space

The following object is masked from ‘package:S4Vectors’:

    space

The following object is masked from ‘package:stats’:

    lowess

在另一个包裹上，

if (!require("Rmixmod", quietly = T)){
    sink("/dev/null")
    suppressPackageStartupMessages(suppressWarnings(suppressMessages(install.packages("R_packages/Rmixmod_2.0.1.tar.gz", type="source"))))
}

我也在加载时获得引用选项，我也试图将其静音。

Rmixmod version 2.0.1 loaded
R package of mixmodLib version 3.0.1

如何才能做到这一点？

Answer 1

不确定是否有人仍在寻找这个问题的答案，但是

suppressWarnings(suppressMessages(library("dplyr")))

作品完美的Jupyter笔记本电脑。我通常定义一个这样的函数：

import_library = function(lib_name){
    suppressWarnings(suppressMessages(require(lib_name, character.only = TRUE)))
}
import_library('dplyr')

请注意，在用户定义的函数内部，library(...)将不起作用，因此请使用require(...). 这character.only = TRUE对于规避 R 尝试加载lib_name为库的名称，而不是实际的库（在我们的例子中dplyr）也是必要的。
