Process and analyze electronic health record (EHR) data. The 'EHR'
package provides modules to perform diverse medication-related studies using
data from EHR databases. Especially, the package includes modules to perform
pharmacokinetic/pharmacodynamic (PK/PD) analyses using EHRs, as outlined in
Choi, Beck, McNeer, Weeks, Williams, James, Niu, Abou-Khalil, Birdwell, Roden,
Stein, Bejan, Denny, and Van Driest (2020) <doi:10.1002/cpt.1787>. Additional
modules will be added in future. In addition, this package provides various
functions useful to perform Phenome Wide Association Study (PheWAS) to explore
associations between drug exposure and phenotypes obtained from EHR data, as
outlined in Choi, Carroll, Beck, Mosley, Roden, Denny, and Van Driest (2018)
<doi:10.1093/bioinformatics/bty306>.
