[rapsimng](https://rapsimng.bangyou.me) package is designed to modify and run the *.apsimx simulations using R in [APSIM Next Generation](https://www.apsim.info/).
## Features
* Find elements in the *.apsimx file
## Installation
Install from CRAN.
```r
install.packages('rapsimng')
```
Install the developing version from [Github](https://github.com/byzheng/rapsimng).
```r
remotes::install_github('byzheng/rapsimng')
```
## Read APSIMX file
The `wheat.apsimx` in the validation dataset of APSIM NG is used as an example. Function `read_apsimx` is used to read `*.apsimx` file through `jsonlite::read_json` and returns as a list.
```r
# Read Wheat.apsimx file with `read_apsimx` which returns a list of json results.
file <- system.file("extdata/wheat.apsimx", package = "rapsimng")
m <- read_apsimx(file)
```
## Search by of APSIM NG
A node in the apsimx file can be found using the path specification in APSIM NG.
```r
potential <- search_path(m,
path = '[Structure].BranchingRate.PotentialBranchingRate.Vegetative.PotentialBranchingRate')
potential
```
## Modify a found model
```r
new_model <- potential$node
new_model$XProperty <- 'NewVariable'
```
## Replace the new model
```r
new <- replace_model(m, potential$path, new_model)
```
## Save into a new apsimx file
```r
write_apsimx(new, tempfile(fileext = '.json'))
```
## Run apsimx file
A function `run_models` is wrapped for APSIM NG `Models.exe` in the command line and can be called to run apsimx files. See [APSIM website](https://apsimnextgeneration.netlify.app/) for documentation.
