Examples

demo_data <- data.frame(subj_id=c(4.1,4.2,5.1,6.1),
                        pat_id=c(14872,14872,24308,37143),
                        gender=c(1,1,0,1),
                        weight=c(34,42,28,63),
                        height=c(142,148,120,167))

# crosswalk w/ same format as idCrosswalk() output
xwalk <- data.frame(subj_id=c(4.1,4.2,5.1,6.1),
                    pat_id=c(14872,14872,24308,37143),
                    mod_visit=c(1,2,1,1),
                    mod_id=c(1,1,2,3),
                    mod_id_visit=c(1.1,1.2,2.1,3.1))

demo_data_deident <- pullFakeId(demo_data, xwalk, 
                                firstCols = c('mod_id','mod_id_visit','mod_visit'),
                                uniq.id='pat_id')
