使用R中的compare.linkage比较两个数据帧并创建对以输入数据

Question

I'm trying to input some data in my dataset based in another one. However, to do this I need to compare several variables and each one has a weight. Also, I need to form pairs using the KEY variables, which are the id in my data.

I was trying to use compare.linkage , but I couldn't find a way to insert the weights that I want eg 40% to Age , 40% to CHBORN , and 20% to URBAN .

Complete <- data.frame(KEY = c(001, 002, 003), AGE = c(35, 38, 45), CHBORN = c(2, 3, 4), URBAN = c(1, 2, 2))

incomplete <- data.frame(KEY = c(004, 005, 006), AGE = c(25, 38, 45), CHBORN = c(1, 2, 4), URBAN = c(2, 1, 1))

KEY_Pairs <- compare.linkage(incomplete, complete, blockfld = c(2, 3, 4), strcmp = TRUE, strcmpfun = levenshteinSim()) #I stopped here

I want to find a result similar to this:

KEY_incomplete KEY_complete Scores   
  004             001        0.95

Usually, I do this using the software FRIL from Emory University, but I'm trying to concentrate everything in R .

Best,
