The **spatialDE** package provides an R wrapper for the Python SpatialDE library,
using `r BiocStyle::CRANpkg("reticulate")` and `r BiocStyle::Biocpkg("basilisk")`.

[SpatialDE](https://github.com/Teichlab/SpatialDE), by [Svensson et al., 2018][Svensson2018],
is a method to identify spatially variable genes (SVGs) in spatially resolved transcriptomics data.

This package started as part of the
[BiocSpatialChallenges](https://helenalc.github.io/BiocSpatialChallenges/index.html).


## Installation instructions

Get the latest stable `R` release from [CRAN](http://cran.r-project.org/). Then
install `r BiocStyle::Biocpkg("spatialDE")` from
[*Bioconductor*](http://bioconductor.org/) using the following code:

```{r 'install', eval = FALSE}
if (!requireNamespace("BiocManager", quietly = TRUE)) {
    install.packages("BiocManager")
}

BiocManager::install("spatialDE")
```

The development version of **spatialDE** can be installed from
[GitHub](https://github.com/sales-lab/spatialDE) with:

```{r 'install_dev', eval = FALSE}
if (!requireNamespace("BiocManager", quietly = TRUE)) {
    install.packages("BiocManager")
    
BiocManager::install("sales-lab/spatialDE")
```


## Basic usage

```{r usage, eval=TRUE}
library(spatialDE)
spe <- mockSVG(return_SPE = TRUE)
de_results <- spatialDE(spe)
head(de_results)
```


## Citation

Below is the citation output from using `citation('spatialDE')` in R. Please
run this yourself to check for any updates on how to cite __spatialDE__.

Please note that this package merely provides a wrapper to use the original Python methods in R. If you find these methods useful, please also consider citing the [original paper][Svensson2018].

```{r 'citation', eval = requireNamespace('spatialDE'), echo = FALSE, comment = ""}
print(citation('spatialDE'), bibtex = TRUE)
```


## Code of Conduct
