一次分离多个包裹 [英] Detach several packages at once

问题描述

受this answer的启发，我正在寻找一种同时分离多个包的方法.

Inspired by this answer I am looking for a way to detach several packages at once.

当我加载时说 Hmisc，

When I load say Hmisc,

# install.packages("Hmisc", dependencies = TRUE)
require(Hmisc)

R 还加载 survival 和 splines.我的问题是是否有办法一起卸载该组?

R also loads survival and splines. My question is if there is a way to unload that group together?

我目前正在做这样的事情，

I currently do something like this,

detach(package:Hmisc, unload = T) 
detach(package:survival, unload = T) 
detach(package:splines, unload = T)

我试过了，

detach(package:c('Hmisc', 'survival', 'splines'), unload = T)

…

推荐答案

另一种选择:

Vectorize(detach)(name=paste0("package:", c("Hmisc","survival","splines")), unload=TRUE, character.only=TRUE)
