R-使用Stringr查找并替换字符串

Question

我正在尝试查找并替换由字符串组成的数据框架的某些值。像以下工作一样的简单情况，

library(stringr)
test1 <- c("one", "two", "three")
str_replace_all(string = test1,
                pattern = c('one' = "1ne",
                            'three' = "3ree"))
> [1] "1ne"  "two"  "3ree"

但是，一个更复杂的案例(如以下情况(不起作用。我在这里做错了什么？

test2 <- c("one (1) x1", "two (2) x2", "three (3) x3")
test2 <- c("one (1) x1", "two (2) x2", "three (3) x3")
str_replace_all(string = test2,
                   pattern = c('one (1) x1' = "X1",
                               'two (2) x2' = "X2"))
> [1] "one (1) x1"   "two (2) x2"   "three (3) x3"

Answer 1

使用修复以避免正则匹配

str_replace_all(string = test2,
                pattern = fixed(c('one (1) x1' = "X1",
                          'two (2) x2' = "X2")))
# [1] "X1"           "X2"           "three (3) x3"
