The functions included in this package are aimed at simplifying the process of running a simulation, changing the value of a variable/parameter and running the model again iteratively. In following steps the goal could be, for example, to either perform sensitivity or uncertainty analysis using R. It is recommended that you start by creating an. There is another function that might be useful inspect_apsimx_json which can be more flexible and a variation of grep grep_json_list.
Inspect_apsimx( "Maize-edited.apsimx", src.dir = ".", node = "Soil", soil.child = "Organic") # Soil Type: Clay (See the help page - ?inspect_apsimx - for more options). The function ‘inspect_apsimx’, in this example, displays various information about the organic matter in the soil. # |Depth |Thickness |Carbon |SoilCNRatio |FBiom |FInert |FOM | # Soil children: Physical SoilWater Organic Chemical InitialWater InitialN CERESSoilTemperature Nutrient

The functionality in apsimx goes beyond that in the removed ‘APSIM’ package. The ‘APSIM’ package was especially useful for creating weather (‘.met’) files. Another useful R package used to be ‘APSIM’, but it has been removed from CRAN (as of ) but as with ‘apsimr’ it has not been updated and it has somewhat of a different functionality. However, that package has not been maintained in the last five years and it does not work for the new APSIM-X framework. That package made it possible to not only run APSIM from R, but also to perform sensitivity analysis and model emulation using ‘GAMS’. In part this package is inspired by previous work by Bryan Stanfill on the ‘apsimr’ package (previously available from CRAN and github: ). If you have any questions write to: femiguez at.
The package is currently being developed and available at. If you need to write scripts (regardless of whether you use the apsimx package or not) the vignette ‘writing scripts’ might be useful. To run simulations the apsimx function ( apsim for ‘Classic’) is available and results from the simulation can be imported as an R object with a dedicated function ( read_apsimx ‘NG’ and read_apsim for ‘Classic’). For ‘inspect’ and ‘edit’ in the APSIM ‘Classic’ version I use the ‘xml2’ package. APSIM ‘Classic’ used an XML format and this type is now fully supported (‘inspect’, ‘edit’, ‘run’ and ‘read’). By using the ‘jsonlite’ R package apsimx can read and write (‘inspect’ and ‘edit’) files in this format. apsimx files are based on the JSON (JavaScript Object Notation ) format and it is used to communicate information to the APSIM-X engine. Are you a user of APSIM-X (“Next Generation”)? Are you a frequent user of R? Are you hoping for APSIM-X and R to interact with each other? Then the answer is the apsimx package, which allows you to inspect, edit, run and read files created by APSIM-X –.
