Examples

## connect to a test database
extdata_dir <- system.file("extdata", package="bioassayR")
sampleDatabasePath <- file.path(extdata_dir, "sampleDatabase.sqlite")
sampleDB <- connectBioassayDB(sampleDatabasePath)

## inspect the structure of the database before forming a query
queryBioassayDB(sampleDB, "SELECT * FROM sqlite_master WHERE type='table'")

## find all activity data for compound cid 2244 
queryBioassayDB(sampleDB, "SELECT * FROM activity WHERE cid = '2244'")

## disconnect from database
disconnectBioassayDB(sampleDB)
