- Hide code


cat("Initiation successful. \n")

out <- op_baseGetData("opasnet_base", "Op_en5682") # Fetches data from Test variable A.

colnames(out)[colnames(out) == "obs.1"] <- "Row" # Changes the column name "obs.1" to "Row"
out <- tidy(out , direction = "wide")
print(out)

Lden <- 60
HA <- ERF_Lden_HA(Lden)
