Examples


library("RJDemetra")

sa_x13 <- jx13(series = ipi_c_eu[, "FR"])
sa_ts <- jtramoseats(series = ipi_c_eu[, "FR"])

wk <- new_workspace()
sap1 <- new_multiprocessing(workspace = wk, name = "sap-1")
add_sa_item(workspace = wk, multiprocessing = "sap-1",
            sa_obj = sa_x13, name = "X13")
add_sa_item(workspace = wk, multiprocessing = "sap-1",
            sa_obj = sa_ts, name = "TramoSeats")

sa_item1 <- get_object(x = sap1, pos = 1L)

remove_sa_item(sap = sap1, pos = 1L) # Remove the first sa-item
add_new_sa_item(sap = sap1, sa_item = sa_item1) # Add the sa-item at the end

# To replace the first sa_item by "sa_item1"
replace_sa_item(sap = sap1, pos = 1L, sa_item = sa_item1)
