【问题描述】：

我希望str_glue 在粘贴时保留\，但我不明白如何逃避它。

我有这个reprex 和我所做的逻辑尝试：（逃避逃逸等）

library(stringr)
var <- "darkness"

str_glue("Hello var my old friend \
I've come to talk with you again")
#> Hello darkness my old friend 
#> I've come to talk with you again

str_glue("Hello var my old friend \\
I've come to talk with you again")
#> Hello darkness my old friend I've come to talk with you again

str_glue("Hello var my old friend \\\
I've come to talk with you again")
#> Hello darkness my old friend I've come to talk with you again

由 reprex 包于 2021-04-28 创建 (v2.0.0)

我想要的输出：

"Hello darkness my old friend \
I've come to talk with you again"

【参考方案1】：

var <- "darkness"
stringr::str_glue("Hello var my old friend \\\ \n I've come to talk with you again")
#> Hello darkness my old friend \ 
#> I've come to talk with you again
