plot {LUCIDus}

Visualize LUCID model through a Sankey diagram

Description

In the Sankey diagram, each node either represents a variable (exposure, omics or outcome) or a latent cluster. Each line represents an association. The color of the node represents variable type, either exposure, omics or outcome. The width of the line represents the effect size of a certain association; the color of the line represents the direction of a certain association. Only work for LUCID early for now.

Usage

plot(x, ...)

Arguments

x

A LUCID model fitted by estimate_lucid

...

Additional arguments to specify colors and fontsize

Value

A DAG graph created by sankeyNetwork

Examples

# prepare data
G <- sim_data$G
Z <- sim_data$Z
Y_normal <- sim_data$Y_normal
Y_binary <- sim_data$Y_binary
cov <- sim_data$Covariate

# plot lucid model
fit1 <- estimate_lucid(G = G, Z = Z, Y = Y_normal, lucid_model = "early", 
CoY = NULL, family = "normal", K = 2, seed = 1008)
plot(fit1)

# change node color
plot(fit1, G_color = "yellow")
plot(fit1, Z_color = "red")

# change link color
plot(fit1, pos_link_color = "red", neg_link_color = "green")
