我想在oner中加载包并同时压缩suppressPackageStartupMessages
。
第一个链接中的答案使用了lapply:
packages <- c("tidyverse", "qdap", "stringr", "stringi", "textstem", "foreach", "caret", "xgboost", "quanteda")
lapply(packages, require, character.only = T)
这会向控制台返回一个难看的列表:
[[1]]
[1] TRUE
[[2]]
[1] TRUE
[[3]]
[1] TRUE
[[4]]
[1] TRUE
另外,我还想摆脱那些在加载时发送到控制台的消息,例如
> library(tidyverse)
Loading tidyverse: ggplot2
Loading tidyverse: dplyr
Conflicts with tidy packages --------------------------------------------------------------------
accumulate(): purrr, foreach
filter(): dplyr, stats
lag(): dplyr, stats
when(): purrr, foreach
是否有一种聪明,简短的方法来加载包矢量和suppressPackageStartupMessages?

答案 2 :(得分:2)
要删除包邮件,您可以使用suppressPackageStartupMessages()
,也可以使用quietly = T
选项:
packages <- c("tidyverse","stringr")
lapply(packages, function(x)require(x, character.only = T, quietly = T))
为了摆脱列表输入,你可以将整个事物包装在invisible()
函数中:
packages <- c("tidyverse","stringr")
invisible(lapply(packages, function(x) require(x, character.only = T, quietly = T)))
答案 3 :(得分:0)
您可以执行以下操作
suppressPackageStartupMessages({
library(ggplot2)
library(tidyr)
})
