setCriteria: Define rules to issue a four level alert...

In AlertaDengue/AlertTools: utility functions for the Infodengue Alert System

Define rules to issue a four level alert Green-Yellow-Orange-Red.

Description

The criteria for transition between colors (alert levels) can be chosen from existing rules or can be specified by the user. The built in rules are: Af (minimum temperature defines yellow) and Aw (humidity does), AsAw (temp min and max humidity together).

Usage

setCriteria(
  rule = NULL,
  values = NULL,
  delays = list(delayy = c(0, 0), delayo = c(0, 0), delayr = c(0, 0))
)

Arguments

rule	either a built-in rule ("Af", "Aw", "AsAw","Awi","AsAwi") or a list with three elements defining criteria for transition to yellow (level 2), orange (level 3) and red (level 4). See description.
values	named vector of values for the critical parameters. Use character.
delays	list with three elements, each one is a vector: c(delay to turn on, delay to turn off)

Value

list with rules. To be useful, this list must contain variables that match those in the data.

Examples

Defining values manually
val <- c("varcli" ="temp_min", "limiar_preseason"="10","limiar_epidemico"="100", "clicrit"="22"
, "clicrit2" = "80", varcli2 = "umid_max")
setCriteria(rule="Af",values=val)
setCriteria(rule="AsAw",values=val)
Using infodengue parameters:
val <- read.parameters(1200401)
setCriteria(rule=val$codmodelo, values=val)
