r - `stringr::str_glue`：如何转义反斜杠（\）？

Question

粘的时候想str_glue留着\，但是不知道怎么逃。

我reprex所做的合乎逻辑的尝试是这样的：（逃避逃跑等）

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

我想要的输出：

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

Answer 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
