mockSVG {spatialDE} | R Documentation

## Generate count matrix for spatially variable genes.

### Description

Generate count matrix for spatially variable genes.

### Usage

    mockSVG(size = 10, tot_genes = 1000, de_genes = 100, return_SPE = FALSE)

### Arguments

`size` | An `integer` scalar. Cells will be spatially arranged on a `size x size` grid. Default: 10, corresponding to 100 cells.
`tot_genes` | An `integer` scalar. Total number of genes. Default: 1000.
`de_genes` | An `integer` scaler. The number of spatially variable genes. Default: 100.
`return_SPE` | A `logical`, whether to return result as a SpatialExperiment. Default: `FALSE`.

### Value

If `return_SPE = TRUE`, returns a SpatialExperiment object.

If not, a `list` containing:

- `coordinates`: `data.frame` with `x` and `y` columns;

- `counts`: `matrix` with generated gene counts.

### Examples

    spe <- mockSVG(10, tot_genes = 200, de_genes = 20, return_SPE = TRUE)
    spe
