我正在解决以下问题,但没有成功:
d <- data.frame(value = 1:4, row.names = c("abc", "abcd", "ef", "gh"))
value
abc 1
abcd 2
ef 3
gh 4
l <- nrow(d)
wordmat <- matrix(rep(NA, l^2), l, l, dimnames = list(row.names(d), row.names(d)))
for (i in 1:ncol(wordmat)) {
rid <- agrep(colnames(wordmat)[i], rownames(wordmat), max = 0)
d$matchid[i] <- paste(rid, collapse = ";")
}
# desired output:
(d_agg <- data.frame(value = c(3, 3, 4), row.names = c("abc;abcd", "ef", "gh")))
value
abc;abcd 3
ef 3
gh 4
有这个功能吗?
