Teal Application Usage Logging. — log_app

Analysis of Teal application utilization is a key component towards ongoing enhancements of the framework. The utilization logs provide source data for better understanding frequency and extent of use.

Usage

log_app_usage(
  ta,
  molecule,
  indication,
  anl_type,
  pkg_meta = c("Package", "Title", "Version", "RemoteRef")
)

Arguments

ta: therapeutic area name. required argument. e.g. "I2ON".
molecule: molecule name. required argument. e.g. "Lucentis".
indication: indication. required argument. e.g. "AMD".
anl_type: analysis type. required argument. e.g. "Interim Analysis".
pkg_meta: package metadata fields. default values: c("Package", "Title", "Version", "RemoteRef").

Details

Each Teal application can implement usage logging by calling this function in the application startup file(s) like app.R. The following data are captured by default: UNIX ID, System Date, Application Directory, Therapeutic Area, Indication, Package Name, Package Title, Package Version and Remotes Definition. Capture frequency is currently per user at session start only. Suggested values for ta: "Oncology" or "I2ON" Suggested values for anl_type: "Exploratory", "Interim Analysis", "CSR"

Examples

if (FALSE) {
log_app_usage(ta = "Oncology", molecule = "Tecentriq", ind = "NSCLC", anl_type = "Exploratory")
readLines(file.path("logs", "utilization.log"), warn = FALSE)
}
