  1. The code below is used for practising; under development.


- Hide code


library(OpasnetBaseUtils)
library(xtable)

cat("Initiation successful. \n")

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

# print(out)
print(xtable(out), type = 'html', html.table.attributes = "class='sortable'")

#mode(out)
#length(out)
#unclass(out)

road_lower_bound <- out[out$Source == "Road" & out$Indicator == "Lden", "Lower bound (dB)"]
road_upper_bound <- out[out$Source == "Road" & out$Indicator == "Lden", "Upper bound (dB)"]
road_exposed <- out[out$Source == "Road" & out$Indicator == "Lden", "Result"]

print(road_exposed)
print(road_lower_bound)
print(road_upper_bound)

# d[d$Row %in% 2:4, ]
# colnames(out)[colnames(out) == "obs.1"]
