[英]Removing loading package message in R
I am using the following packages in my R script:我在 R 脚本中使用以下包:
library(uba)
library(performanceEstimation)
library(UBL)
library(DMwR)
These packages always issue the message: 'loading package xyz'.这些包总是发出消息:'loading package xyz'。 If I don't suppress the 'loading package' messages as I am doing below:如果我不抑制“加载包”消息,就像我在下面做的那样:
suppressPackageStartupMessages(library(operators))
suppressPackageStartupMessages(library(class))
suppressPackageStartupMessages(library(fields))
suppressPackageStartupMessages(library(spam))
suppressPackageStartupMessages(library(dotCall64))
suppressPackageStartupMessages(library(grid))
suppressPackageStartupMessages(library(DMwR))
suppressPackageStartupMessages(library(uba))
suppressPackageStartupMessages(library(UBL))
suppressPackageStartupMessages(library(MBA))
suppressPackageStartupMessages(library(gstat))
suppressPackageStartupMessages(library(automap))
suppressPackageStartupMessages(library(sp))
suppressPackageStartupMessages(library(randomForest))
library(uba) # util used below
library(performanceEstimation)
library(UBL)
library(DMwR)
I get the following messages in my console :我在控制台中收到以下消息:
Loading required package: operators

Is there a way to suppress messages in any other way ?有没有办法以任何其他方式抑制消息? I might be using these packages in many other R scripts and I don't want to do this each time.我可能在许多其他 R 脚本中使用这些包,我不想每次都这样做。
One way is to write a simple function, that takes in a vector of packages and suppresses the output in a way you want, as examplified below.一种方法是编写一个简单的函数,它接收一个包向量并以您想要的方式抑制输出,如下所示。
library_suppress <- function(packages, character.only = TRUE, ...){
for(i in seq_along(packages))
suppressPackageStartupMessages(
library(packages[i], character.only = character.only, ...)
)
}
packages <- c('operators', 'class', 'fields', 'spam', 'dotCall64', 'grid', 'MBA', 'gstat', 'automap', 'sp', 'randomForest')
library_suppress(packages)
Note this does not suppress warning messages.请注意,这不会抑制警告消息。
