Spatial heatmap

Description

Plot spatial heatmap for a Seurat object with spatial transcriptomics data.

Usage

  SpaPlot(seuInt, batch=NULL, item=NULL, point_size=2,text_size=12, 
                    cols=NULL,font_family='', border_col="gray10",
                    fill_col='white', ncol=2, combine = TRUE,
                    title_name="Sample", ...)

an object named "Seurat".

batch

an optional positive integer or integer vector, specify the batches to be extracted. Users can check the batches' names by unique(seuInt$batch).

item
