Feature Plot in Tissue Space

Plots marker expression intensity on spatial coordinates. Each marker gets its own panel. Similar to Seurat's FeaturePlot but in tissue space.

Usage

FeaturePlot(
  object,
  features,
  slot = "data",
  pt_size = 0.3,
  ncol = NULL,
  palette = NULL,
  dark_theme = FALSE
)

Arguments

object

An SpatialCellData object.

features

Character vector. Marker names to plot.

slot

Character. "data" or "counts".

pt_size

Numeric. Point size. Default 0.3.

ncol

Integer. Number of columns in the faceted layout. Default NULL (auto).

palette

Character or character vector. Colour palette. Default NULL uses the global palette.

dark_theme

Logical. Dark background. Default FALSE.

Value

A ggplot object.

Examples

counts <- matrix(rnorm(150), nrow = 50,
                 dimnames = list(NULL, c("CD3", "CD8", "PanCK")))
coords <- data.frame(x = runif(50, 0, 500), y = runif(50, 0, 500))
obj <- CreateSpatialObject(counts, coords)
FeaturePlot(obj, features = c("CD3", "CD8"))
