Question

我已经用Google搜索了，我看到如果我使用suppressPackageStartupMessages()我应该能够解决我的问题，但事实证明，没有任何事情发生。

我正在加载我的包裹：

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"))))
}

我在加载时也得到了引用选项，我也试图让它沉默。

Rmixmod version 2.0.1 loaded
R package of mixmodLib version 3.0.1

如何做到这一点？

Answer 1

不确定是否有人仍在寻找这个问题的答案，但

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

在Jupyter笔记本上完美地。我通常会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，在用户定义的函数中，library(...)将不起作用，因此请使用require(...)。 character.only = TRUE也是必要的，以避免R尝试加载lib_name作为库的名称，而不是实际的库（在我们的例子中dplyr）。

可以找到类似的答案here。
