Get the risk category for each AQHI level

AQHI levels are broken down into categories for easier communication of health risks:

• Low: AQHI = 1-3

• Moderate: AQHI = 4-6

• High: AQHI = 7-10

• Very High: AQHI = "+" (>10)

Health messages for at risk population and general population are available for each risk category - see get_health_messages

Usage

get_risk_category(aqhi_levels = c(1:10, "+"), language = "en")

Arguments

aqhi_levels

(Optional). A vector of AQHI levels (1-10, "+", or NA). Default is all unique levels.

language

(Optional). A single character value indicating the language to use for risk levels and health messaging. Must be either "en" (English) or "fr" (French). Not case sensitive. Default is "en".

Value

A factor of risk categories (Low, Moderate, High, Very High) representing each level of aqhi_levels.
