apsimwise

apsimwise is a collection of interoperable R packages for crop modelling, weather analysis, and agricultural decision support.

The goal of apsimwise is to provide a consistent and user-friendly interface to APSIM-related workflows, allowing researchers, students, breeders, agronomists, and consultants to work with multiple crops using a common set of tools.

Installation

From GitHub for the latest development version:

remotes::install_github("byzheng/apsimwise")

Load apsimwise

library(apsimwise)

Installed Packages

This package installs and loads the core apsimwise ecosystem, including:

• tidyweather for weather data analysis.
• rapsimng for manipulating APSIM Next Generation.
• Packages for specific crops, including:
  • rapsimng.wheat for Wheat
  • rapsimng.canola for Canola
  • rapsimng.chickpea for Chickpea
  • rapsimng.fababean for Faba Bean
  • rapsimng.lentil for Lentil
  • rapsimng.lupin for Lupin
  • additional crop packages as they become available

Get Started

apsimwise re-exports commonly used functions from the ecosystem so that most users only need to load a single package.

library(apsimwise)

# Read weather data
met <- read_weather("weather.met")

# Calculate day length
day_length(
  date = met$date,
  latitude = -27
)

# Calculate thermal time using crop-specific defaults
thermal_time(
  mint = met$mint,
  maxt = met$maxt,
  date = met$date,
  latitude = -27,
  crop = "lupin"
)

# View crop-specific parameters
crop("lupin")$get()

For a complete list of functions, see the package documentation:
