FOCUS_Step_12_scenarios: Step 1/2 scenario data as distributed with the FOCUS Step 1/2...

In jranke/pfm: Utilities for Pesticide Fate Modelling

Step 1/2 scenario data as distributed with the FOCUS Step 1/2 calculator

Description

The data were extracted from the scenario.txt file using the R code shown below. The text file is not included in the package as its licence is not clear.

Format

A list containing the scenario names in a character vector called 'names', the drift percentiles in a matrix called 'drift', interception percentages in a matrix called 'interception' and the runoff/drainage percentages for Step 2 calculations in a matrix called 'rd'.

Examples

## Not run: 
  # This is the code that was used to extract the data
  scenario_path <- "inst/extdata/FOCUS_Step_12_scenarios.txt"
  scenarios <- readLines(scenario_path)[9:38]
  FOCUS_Step_12_scenarios <- list()
  sce <- read.table(text = scenarios, sep = "\t", header = TRUE, check.names = FALSE,
    stringsAsFactors = FALSE)
  FOCUS_Step_12_scenarios$names = sce$Crop
  rownames(sce) <- sce$Crop
  FOCUS_Step_12_scenarios$drift = sce[, 3:11]
  FOCUS_Step_12_scenarios$interception = sce[, 12:15]
  sce_2 <- readLines(scenario_path)[41:46]
  rd <- read.table(text = sce_2, sep = "\t")[1:2]
  rd_mat <- matrix(rd$V2, nrow = 3, byrow = FALSE)
  dimnames(rd_mat) = list(Time = c("Oct-Feb", "Mar-May", "Jun-Sep"),
                          Region = c("North", "South"))
  FOCUS_Step_12_scenarios$rd = rd_mat
  save(FOCUS_Step_12_scenarios, file = "data/FOCUS_Step_12_scenarios.RData")

## End(Not run)

# And this is the resulting data
FOCUS_Step_12_scenarios
