Robust Geographical Detector & Robust Interaction Detector(RGD & RID)

Set up python dependence

  1. Install miniconda

  2. Open the conda terminal and perform steps 3 to 6

  3. Create a new conda env gdverse

    conda create -n gdverse python=3.10 -y

  4. Activate this env

    conda activate gdverse

  5. Install mamba

    conda install -c conda-forge mamba -y

  6. Set up python packages

    mamba install -c conda-forge numpy joblib pandas ruptures -y

  7. Configure GDVERSE_PYTHON environment variable

    • Temporarily setting up gdverse python dependence environment using Sys.setenv() in the R console or R code like Sys.setenv(GDVERSE_PYTHON = "path/to/python/environment").

    • Or using usethis::edit_r_environ() to set long-available gdverse python dependencies environment path.

Load data and package

library(tidyverse)
library(gdverse)

data("ndvi")
names(ndvi)
## [1] "NDVIchange"    "Climatezone"   "Mining"        "Tempchange"    "Precipitation" "GDP"          
## [7] "Popdensity"

Run RGD

ndvi_rgd = rgd(NDVIchange ~ ., data = ndvi,
               discvar = names(dplyr::select(ndvi,-c(NDVIchange,Climatezone,Mining))),
               discnum = 3:8, cores = 12)
ndvi_rgd

## |      GDP      |  0.1164814  | 1.08e-10 |

Run RID

RID allows you to obtain the interactions of all possible combinations of variables. By default, Spatial Intersection are used to generate a new spatial partition of the interaction variables.

ndvi_rid = rid(NDVIchange ~ ., data = ndvi,
               discvar = names(dplyr::select(ndvi,-c(NDVIchange,Climatezone,Mining))),
               discnum = 8, cores = 12)
