Data on the rice yields in the Vietnamese provinces

Source: R/CoDaImpact-package.R
rice_yields.Rd

The data is presented in Trinh et al. (2023) for studying the impact of climate change on rice production in Vietnam.
It contains the following information:

  • PROVINCE: a factor for the 63 provinces of Vietnam

  • REGION: a factor with the 6 main regions

  • YEAR: a numeric corresponding to the year

  • YIELD: a numeric for the rice production in tons per hectare

  • PRECIPITATION: a numeric for the annual precipitation in liters

  • TEMPERATURES: a compositional variable represented as a matrix
    whose columns correspond to the proportion of days in a year where the maximal temperature (in Celsius degrees) falls into one of the three categories: "LOW" (from -6, to 25.1), "MEDIUM" (from 25.1 to 35.4) and "HIGH" (from 35.4 to 45).

Usage
