I would like to create pseudo identification numbers in the format of last four of a social security number (0000 to 9999), month of birth (01 to 12), and day of birth (01-28). The IDs can be character.
I have gotten this far: for (ssn in 0:9){ for (month in 1:3){ for (day in 1:5){ } id <-paste(ssn, month, day, sep="") } } limiting each value above for demonstration purposes. I cannot figure out how to store the created IDs. I know I have to create a container, but I don't know, among other things, how to index the container. Any help is appreciated.
