PEcAn Functions Used for Ecological Forecasts and Reanalysis using MAESPA
Installation
You can install the development version of PEcAn.MAESPA from r-universe like so:
# Enable repository from pecanproject
options(repos = c(
pecanproject = 'https://pecanproject.r-universe.dev',
CRAN = 'https://cloud.r-project.org'))
# Download and install PEcAn.MAESPA in R
install.packages('PEcAn.MAESPA')Or you can install directly from GitHub with the remotes package like so:
library(remotes)
install_github('pecanproject/pecan', subdir = "models/maespa")When writing configurations files PEcAn.MAESPA uses the Maeswrap package. We recommend Maeswrap 1.8.0 or later, which you can install from GitHub with remotes::install_github("RemkoDuursma/Maeswrap"). An older version of Maeswrap (1.7 at this writing in September 2024) is also available from CRAN and does provide the functionality PEcAn.MAESPA needs, but this version has a strong dependency on the rgl package, which can be hard to install and are not needed by PEcAn. If you have trouble installing the extra dependencies or if you are annoyed by an unwanted plot window opening every time you use PEcAn.MAESPA, try upgrading Maeswrap to 1.8 or later.
Example
This is a basic example which shows you how to solve a common problem:
