Set up python dependence
Install miniconda
Open the conda terminal and perform steps 3 to 6
-
Create a new conda env
gdverse
conda create -n gdverse python=3.10 -y
-
Activate this env
conda activate gdverse
-
Install
mamba
conda install -c conda-forge mamba -y
-
Set up python packages
mamba install -c conda-forge numpy joblib pandas ruptures -y
-
Configure
GDVERSE_PYTHON
environment variableTemporarily setting up
gdverse
python dependence environment usingSys.setenv()
in the R console or R code likeSys.setenv(GDVERSE_PYTHON = "path/to/python/environment")
.Or using
usethis::edit_r_environ()
to set long-availablegdverse

Run RGD

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(select(ndvi,-c(NDVIchange,Climatezone,Mining))),
discnum = 10, cores = 12)
