execute with parsed arguments

run(optdate, opttest)

main function which encapsulates high level functions of your program

run <- function(date, test) { readData(...) transformData(...) trainModel(...) ifelse(test, dbfaker::verifyWrite(...), writeData(...)) }

components of your program

readData <- function(...) {} transformData <- function(...) {} trainModel <- function(...) {} writeData <- function(...) { dbWriteTable(...) dbSendQuery(...) } ```
