dm (version 0.0.3.9003)

cdm_nycflights13: Creates a dm object for the nycflights13 data

Description

Creates an exemplary dm object from the tables in nycflights13 along with the references. See nycflights13::flights for a description of the data. As described in nycflights13::planes, the relationship between the flights and planes tables is "weak", it does not satisfy data integrity constraints.

Usage

cdm_nycflights13(cycle = FALSE, color = TRUE)

Arguments

cycle

Boolean. If FALSE (default), only one foreign key relation (from flights$origin to airports$faa) between flights and airports is established. If TRUE, a dm object with a double reference between those tables will be produced.

color

Boolean, if TRUE (default), the resulting dm object will have colors assigned to different tables for visualization with cdm_draw()

Examples

Run this code
# NOT RUN {
if (rlang::is_installed("nycflights13")) {
  cdm_nycflights13() %>%
    cdm_draw()
}
# }
