Description

Takes Client, removes records where SSNs are invalid, then links the PersonalIDs based upon matching SSNs. The Client is returned with a column called PrimaryPersonalID which should be a more unique identifier than the PersonalID alone.

Usage

linkPersonalIDBySSN(client, primaryPersonalIDsOnly = FALSE)

Arguments

primaryPersonalIDsOnly	Default false. Returns a dataframe of only PrimaryPersonalIDs and PersonalIDs
dataframe	path to folder contaning first CSV set.

Examples

clientDf1 <- data.frame(PersonalID=c("ZP1U3EPU2FKAWI6K5US5LDV50KRI1LN7", 
                      "IA26X38HOTOIBHYIRV8CKR5RDS8KNGHV", 
                      "LASDU89NRABVJWW779W4JGGAN90IQ5B2"),

                      LastName=c("Tesa", "Falla", "Kerrigan"),
                      SSN=c("123456789", "123456789", "987654321"))

clientDf2 <- getPrimaryPersonalID(clientDf1)
# Remove the old PersonalID
clientDf2 <- within(clientDf2, rm(PersonalID))
colnames(clientDf2)[1] <- "PersonalID"
# Get a deduplicated Client
clientDf2 <- unique(clientDf2)
