scMetaTraj (version 0.1.1)

scMetaTraj_plot_trend_multi: Plot multiple module trends with switchpoints

Description

Visualize metabolic module trends along pseudotime with identified switchpoints marked by vertical dashed lines.

Usage

scMetaTraj_plot_trend_multi(trend_long, switchpoints)

Value

A ggplot2 object showing trends faceted by module.

Arguments

trend_long

Data frame with columns: module, mPT_bin, score_smooth. Output from scMetaTraj_trend_multi()$trend_long.

switchpoints

Data frame with columns: module, mPT_switch. Output from scMetaTraj_trend_multi()$switchpoints.

Examples

# Create example trend data
trend_long <- data.frame(
  module = rep(c("Glycolysis", "OXPHOS"), each = 30),
  mPT_bin = rep(seq(0, 1, length.out = 30), 2),
  score_smooth = c(sin(seq(0, pi, length.out = 30)),
                   cos(seq(0, pi, length.out = 30)))
)

# Create example switchpoint data
switchpoints <- data.frame(
  module = c("Glycolysis", "OXPHOS"),
  mPT_switch = c(0.5, 0.3)
)

# Plot
p <- scMetaTraj_plot_trend_multi(trend_long, switchpoints)
print(p)
