Thanks, everyone!

Oops, I sent this to Tom earlier today and forgot to copy to the list: VendorID=rep(paste0("V",1:10),each=5) AcctID=paste0("A",sample(1:5,50,TRUE)) Data<-data.frame(VendorID,AcctID) table(Data) # get multiple vendors for each account dupAcctID<-colSums(table(Data)>0) Data$dupAcct<-NA # fill in the new column for(i in 1:length(dupAcctID)) Data$dupAcct[Data$AcctID == names(dupAcctID[i])]<-dupAcctID[i] Jim On Wed, Nov 18, 2020 at 8:20 AM Tom Woolman <twool...@ontargettek.com> wrote:Hi everyone. I have a dataframe that is a collection of Vendor IDs plus a bank account number for each vendor. I'm trying to find a way to count the number of duplicate bank accounts that occur in more than one unique Vendor_ID, and then assign the count value for each row in the dataframe in a new variable. I can do a count of bank accounts that occur within the same vendor using dplyr and group_by and count, but I can't figure out a way to count duplicates among multiple Vendor_IDs. Dataframe example code: #Create a sample data frame: set.seed(1) Data <- data.frame(Vendor_ID = sample(1:10000), Bank_Account_ID = sample(1:10000)) Thanks in advance for any help. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.[[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
