Show me the code

To evaluate the soil characteristics of the land units of Marinduque, Philippines, for farming banana, use the suit function as follows:

library(ALUES)
suit_banana <- suit("banana", terrain=MarinduqueLT)
head(suit_banana[["soil"]]$`Suitability Score`)
head(suit_banana[["soil"]]$`Suitability Class`)

To compute the overall suitability of the land units by averaging across factors, use the overall_suit as follows:

osuit <- overall_suit(suit_banana[["soil"]], method="average")
head(osuit)

Show me the speed

The elapsed time for computing the suitability scores and classes were recorded for the land units of Marinduque, which has 881 units (or observations) in total; and, for the region of Lao Cai, Vietnam, which has 2928 land units.

library(microbenchmark)
microbenchmark(
  suppressWarnings(suit("banana", terrain=MarinduqueLT, interval="unbias"))
)
microbenchmark(
  suppressWarnings(suit("banana", terrain=LaoCaiLT, interval="unbias"))
)
