Visualize spatial patterns of a single gene

Usage

plotGene(
  expr,
  clufitRes = NULL,
  coord,
  sc,
  gene,
  cellclu = NULL,
  background = FALSE,
  ...
)

expr: The normalized gene expression matrix
clufitRes: The output from ctsvg_fit (NULL by default, original gene expression matrix)
coord: The matrix of spatial locations
sc: The named vector of cell cluster assignments
gene: Which gene to plot
cellclu: A character value indicating which cell cluster to plot (NULL by default, all cells)
background: Whether to plot all cells (FALSE by default)
...: The parameters in the geom_point(...) function
