Using RecordLinkage to add a column with a number for each person

Question

I\'d like to do what I think is a very simple operation -- adding a column with a number for each person to a dataset with a list of (potentially) duplicative names. I think

Answer 1

small rewrite avoiding that the weights and classifier have to be tuned with the IDs,

df_names <- data.frame(Name=c("Peter","Peter","Peter","Connor","Matt"))

df_names %>% compare.dedup() %>%
             epiWeights() %>%
             epiClassify(0.3) %>%
             getPairs(show = "links", single.rows = TRUE) -> matches

left_join(mutate(df_names,ID = 1:nrow(df_names)), 
          select(matches,id1,id2) %>% arrange(id1) %>% filter(!duplicated(id2)), 
          by=c("ID"="id2")) %>%
    mutate(ID = ifelse(is.na(id1), ID, id1) ) %>%
    select(-id1)
