抑制包加载消息

Question

我已经在谷歌上搜索过，我发现如果我使用suppressPackageStartupMessages()，我应该能够解决我的问题，但事实证明，什么都没有发生。

我把包裹装成这样：

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，我会收到以下消息：

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

在另一个包裹里，

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

在加载时，我也会得到引文选项，而且我也试图让它安静下来。

Rmixmod version 2.0.1 loaded
R package of mixmodLib version 3.0.1

这是如何做到的呢？

Answer 1

不知道是否还有人在找这个答案，但是

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

在木星笔记本上工作得很好。我通常定义如下函数：

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

注意，在用户定义的函数中，library(...)不能工作，所以使用require(...)。为了避免R将character.only = TRUE作为库的名称加载，而不是实际的库(在我们的例子中是dplyr)，lib_name也是必要的。

here也有类似的答案。
