Arguments
.data |
A |
drug_s |
A character string. The name of the drug column. Drug columns can be created with |
adr_s |
A character string. The name of the adr column. Adr columns can be created with |
Details
Counts are provided at the case level (not the drug-adr pair level).
Description span from number of rechallenge cases
to informative rechallenge cases (those cases where the outcome is known).

data.table, see link_
, on which
you have added drugs and adrs with add_drug()
and add_adr()
.
