REPLACE(char,search_string[, replacement_string]) 解释一下: 在replace中,每个search_String 都会被replacement_string替换掉,而replacement_string可以为null或者空字符串,search_String会被移除,而如果search_String为空字符串时,会返回原来的字符串。 ①当replacement_string=null或者replacement_string=‘’: select ...

这个问题可能在stringr::str_replace_all有那个选项(或众所周知)之前寻求类似的答案。我正在复制下面我的答案的要点,使用str_replace_all. tr <- c("whatevs_1", "something_52", "whatevs_1something_52")tr#> [1] "whatevs_1" "something_52" "whatevs_1something_52"patterns <- sprintf('_%s$',...
