如何删除r字符串中的某些字符
如何删除r字符串中的某些字符
提问于 2020-02-25 15:31:45
我想删除字符：“(平均(SD))"，我使用了3种方法，但它们都没有成功。我也不知道原因。
names <- c("Y_OR_N (mean (SD))", "age (mean (SD))", "101004A (mean (SD))", "101016 (mean (SD))", "209003 (mean (SD))", "210005 (mean (SD))", "GFR (mean (SD))", "307001 (mean (SD))", "308001 (mean (SD))", "308014 (mean (SD))")
names %>% str_remove(pattern = " (mean (SD))")
names %>% str_replace(pattern = " (mean (SD))", replacement = "")
names %>% gsub(x = ., pattern = " (mean (SD))", replacement = "") 任何帮助都将不胜感激！

您可以使用gsub + trimws (可选)尝试下面的代码，即，
trimws(gsub("(mean (SD))","",names,fixed = TRUE))这样的话
> trimws(gsub("(mean (SD))","",names,fixed = T))
[1] "Y_OR_N" "age" "101004A" "101016" "209003"
[6] "210005" "GFR" "307001" "308001" "308014" Stack Overflow用户

括号是特殊的，尝试用\\转义它们
names %>% str_remove_all(pattern = " \\(mean \\(SD\\)\\)")页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
