R：模糊合并两个数据框

Question

我有2个数据框。

首先，

abc <- data.frame(bin1 = c("0-25K", "25K-50K", "50K+"), group1 = c(1, 1, 2), bin2 = c("0-25", "25-50", "50+"), group2 = c(1, 2, 2))

pqr <- data.frame(bin1 = c("1_0-25K", "2_25K-50K", "3_50K+"),bin2 = c("0,25", "25,50", "50+"))

我想合并abc和pqr得到

pqr <- data.frame(bin1 = c("1_0-25K", "2_25K-50K", "3_50K+"), group1 = c(1, 1, 2), bin2 = c("0,25", "25,50", "50+"), group2 = c(1, 2, 2))

我查看了一些较早发布的问题，但其中 none 对我有用。

Merging two Data Frames using Fuzzy/Approximate String Matching in R

Answer 1

这个有效：

library(fuzzyjoin)
pqr <- pqr %>% stringdist_inner_join(abc, by = c(bin1 = "bin1"))
