sa_model <- x13(ipi_c_eu[, "FR"], "RSA5c")
dashboard_data <- sc_dashboard(sa_model)
plot(dashboard_data, main = "Statistics Canada dashboard",
subtitle = "SA with X13")
dashboard_data <- simple_dashboard(sa_model)
plot(dashboard_data, main = "Simple dashboard - IPI FR")
simple_dashboard2() is a slightly variation of simple_dashboard() with smaller description text to include a table with last outliers:
dashboard_data <- simple_dashboard2(sa_model)
plot(dashboard_data, main = "Simple dashboard with outliers - IPI FR")
