Plot Cell Type Ratio Along Distance from Niche Center

Visualizes the fraction of cell types as a function of distance from niche centers, with distance binning based on spatial coord_intervals.

Usage

Plot_DistLine_Ratio(
  STID_obj = NULL,
  loop_id = "LoopAllSamp",
  meta_key = NULL,
  group_by = NULL,
  facet_grpnm = NULL,
  celltypes = NULL,
  coord_interval_ratio = NULL,
  linewidth = 1,
  ncol = 4,
  col = COLOR_LIST[["PALETTE_WHITE_BG"]]
)

Arguments

STID_obj

An STID object containing niche analysis results

loop_id

Character, sample grouping identifier (default: "LoopAllSamp")

meta_key

Character, metadata key containing distance information

group_by

Character, column name for cell type grouping

facet_grpnm

Character, column name for faceting

celltypes

Character vector, cell types to plot

coord_interval_ratio

Numeric, multiplier for coord_interval to set bin width

linewidth

Numeric, line width (default: 1)

ncol

Integer, number of facet columns (default: 4)

col

Color palette (default: COLOR_LIST$PALETTE_WHITE_BG)

Value

A ggplot object

Examples

if (FALSE) { # \dontrun{
# Plot cell type ratios along distance from niche center
Plot_DistLine_Ratio(
  STID_obj = STID_obj,
  celltypes = c("Tcell", "Bcell", "Macrophage"),
  group_by = "cell_type",
  meta_key = "M2_NicheDetect_STS_20240101",
  coord_interval_ratio = 5
)
} # }
