基于部分匹配替换整个字符串 [英] Replace entire strings based on partial match

问题描述

R 新手.如果有部分匹配，则希望替换整个字符串.

New to R. Looking to replace the entire string if there is a partial match.

d = c("SDS0G2 Blue", "Blue SSC2CWA3", "Blue SA2M1GC", "SA5 Blue CSQ5")

gsub("Blue", "Red", d, ignore.case = FALSE, fixed = FALSE)

输出:SDS0G2红色"红色SSC2CWA3"红色SA2M1GC"SA5红色CSQ5"

Output: "SDS0G2 Red" "Red SSC2CWA3" "Red SA2M1GC" "SA5 Red CSQ5"

期望输出:红"红"红"红"

推荐答案

我建议使用 grepl 来查找索引并将这些索引替换为Red":

I'd suggest using grepl to find the indices and replace those indices with "Red":

d = c("SDS0G2 Blue", "Blue SSC2CWA3", "Blue SA2M1GC", "SA5 Blue CSQ5", "ABCDE")
d[grepl("Blue", d, ignore.case=FALSE)] <- "Red"
d
# [1] "Red"   "Red"   "Red"   "Red"   "ABCDE"
