apsimx 2.8.0 - 2024-08-19

• Many changes to inspect, extract and edit to better support ‘InitialWater’ and ‘Solutes’. There is significant testing, but more is needed.

• New function ‘check_apsimx’ that will try to identify common issues in apsimx files

• apsimx_example can now run several other examples

• There is an option to run files which are in directories with spaces. This is experimental as it can fail in some cases. See ‘apsimx_options’.

• Improvements to the code that runs ‘sens_apsimx’ in parallel

• Implemented ‘id’ and ‘id.labels’ in plot for compare_apsim

• Package ‘FedData’ was removed from ‘Suggests’ as it was removed from CRAN (8-19-2024). It has not been used in the ‘apsimx’ package for a long time.

apsimx 2.7.7

• sens_apsimx can now accept an argument called ‘soil.profiles’. This opens the door for conducting simulations on a spatial grid, by carefully passing weather and soils profiles. Since now package ‘future’ is used for parallelization, this makes it easy to run it on a parallel environment.

• sens_apsimx cores argument now requires package ‘future’. This was done to support both unix and windows.

• edit_apsimx Editing different simulations used to require specifying ‘root’. Now if the parameter path is complete, this is not required. In this case node should equal “Other”

• check_apsim_met checks presence and values of tav and amp. New tav_apsim_met function can be used to calculate and insert tav in an APSIM met file

• inspect_apsimx is a bit more robust. When node = “Other” the simulation structure will be displayed according to the value of parm (0, 1, 2). If ‘parm’ is a parameter path, the root elements will be ‘guessed’ from the string.

apsimx 2.6.2 - 2024-01-28

• Most change are to adjust to new structure in the APSIM simulations
• soil profiles now can contain an object of class ‘initialwater_parms’ that can be used to set the initial water. This caused problems in the past because of changing ‘physical’ without changing the initial water
• unexported function get_worldmodeler_soil_profile

apsimx 2.5.1 - 2023-12-10

• Some of the changes are due to changes in APSIM Next Gen
• Need to add alternative ‘root’ for replacements

apsimx 2.3

• Fixed bug in napad_apsim_met and also wrote more extensive tests (test_apsim_met)
• Added method confint for optim_apsim class and fixed bug related to this issue
• Added package ‘ucminf’ as an additional optimization type
• optim functions data argument data frame can contain missing data
• function get_daymet_apsim_met (which used to depend on the FedData package) is deprecated. It has been replaced by the previous get_daymet2_apsim_met function.
• remove use of raster package

apsimx 2.2

• By deault it runs for newer versions of APSIM Next Gen (Sep 2021 or newer) (Classic is unchanged)
• For Mac and Linux, you might need to set ‘mono = TRUE’ for compatibility with older versions of APSIM Next Gen
• New functions: plot.met and summary.met for ‘met’ objects
• New function: carbon_stocks for calculating carbon stocks for an object of class ‘soil_profile’
• New functions: comparing soil profiles ‘compare_apsim_soil_profile’ and associated plot function
• More options in ‘unit_conv’ function.
• Edits to writing scripts vignette
• Various bug fixes and improvements.

apsimx 2.0

• Sensitivity analysis functions for APSIM Next Gen and Classic
• Parameter Estimation functions for APSIM Next Gen and Classic
• Work in progress function inspect_apsimx_json for .json or .apsimx files
• Helper function (grep_json_list - not needed for most users)
• Unreleased edit_apsimx_json function.
• Various bug fixes in edit and inspect functions
• Creating synthetic soil profiles from ISRIC (get_isric_soil_profile)
• Depracated get_daymet_apsim_met (replaced with get_daymet2_apsim_met)
• Creating synthetic soil profile from SSURGO (get_ssurgo_soil_profile and get_ssurgo_tables)
• Passing extra arguments to APSIM call through xargs_apsimx

apsimx 1.977

• Much improved handling of APSIM-X output. However, this led to some default changes. Argument ‘value’ in function ‘apsimx’ and ‘read_apsimx’ is ‘report’ instead of ‘all’. The default for ‘apsim’ was also changed for consitency. Hopefully, this will not impact too many scripts.

• Multi-site optimization is now possible (for Classic and Next Gen). In this case, the index argument likely needs to be adjusted to ‘index = c(“outfile”, “Date”) for ’Classic’ and ‘index = c(“report”, “Date”)’ for ‘Next Generation’

• Several improvements to ‘get’ functions for fetching weather data.

• Fixed bug when using ‘root’ argument in ‘edit_apsim’
