str_remove到多行字符串的末尾

Question

如何将纵梁移除到多行文档的末尾？

require(stringr)
x = 'The quick brown
fox jumps over
the lazy dog'

str_remove(x, regex('jumps.*', multiline = TRUE)) %>% cat
#> The quick brown
#> fox 
#> the lazy dog

Answer 1

该解决方案如何？

library(stringr)
library(dplyr)

x = 'The quick brown
fox jumps over
the lazy dog'

str_replace(x, regex('jumps.*\n*.*'), "") %>% cat

应与：

str_remove(x, regex('jumps.*\n*.*')) %>% cat
