Usage

To run the TrajectoryViz graphical interface you can use the following wrapper.

# Initiate database connection & load data
pathToResults <- "./inst/example"
db <- DBI::dbConnect(duckdb::duckdb(), dbdir = CDMConnector::eunomia_dir("GiBleed"))
cdm <- CDMConnector::cdm_from_con(db , cdm_name = "eunomia", cdm_schema = "main", write_schema = "main")
data <- readRDS("./inst/example/example.rds")

# Import raw data for trajectory creation
data <- CohortContrast::createC2TInput(data, cdm)

# Create trajectories
trajectories <- CohortContrast::C2TCaller(
  data,
  pathToResults
)

# Run TrajectoryViz GUI
CohortContrast::runTrajectoryViz(trajectories)
