I am working on a large dataset for a research project. The project includes safety case reports (Adverse Event) and I am trying to apply an inclusion criteria which is:
the adverse event must come from two different sources. the sources are coded in an excel sheet as (1) and (0). To be included the adverse event must come from both sources (1 & 0) to enter into the final analysis. The data is available in excel.
What would be the appropriate codes to run on R in order to apply the criteria?
