Grouping example | Comment |
---|---|
item1 | Group by value in item1. Depending on the domain path this can be used to group per site (cf. Fig. 2), time interval (year, month, quarter, day), day of week, patient etc |
sprintf("%s_%s",item1,item2) | Combines multiple values for grouping, e.g. to get counts of antibiotic resistant isolates per bacteria species in lab values |
