apsimeval: Evaluation, Visualisation and Sensitivity Analysis of 'APSIM'
Classic Output
Reads Agricultural Production Systems sIMulator ('APSIM') Classic
7.x '.out' files, pairs simulated series with sparse observed
measurements, and computes the goodness-of-fit statistics used in
crop-model calibration and validation, including the decomposition of root
mean squared error into systematic and unsystematic components. Produces
publication grade figures with 'ggplot2': one-to-one scatter plots,
residual and Taylor diagrams, probability of exceedance curves,
multi-variable timelines with a secondary axis, and distribution plots,
assembled into multi-panel figures at journal column widths in colour,
greyscale or line art. Treatment structure encoded in simulation names is
parsed into factor columns, and the sensitivity of an output to those
factors is quantified by variance decomposition, one-at-a-time analysis or
range screening. A built-in 'shiny' interface watches the output directory
and refreshes incrementally as 'APSIM' regenerates its files.
