modu=membership(modu_network) - This line assigns the module membership of each node in the network modu_network to the vector modu.

color_value =c("yellow","#66FFFF","#7CCD7C","pink") - This line creates a vector color_value with four colors that will be used to represent the different modules in the network.

V(network)$color = color_value[modu] - This line assigns a color to each vertex in the network based on its module membership. The color_value vector is indexed by the modu vector to get the appropriate color for each vertex.

par(bg="white", mar=c(0,0,0,0)) - This line sets the background color of the plot to white and removes the plot margins.

set.seed(123) - This line sets the random number generator seed used for generating the plot layout to a fixed value, ensuring that the plot will be reproducible.

plot(network,vertex.frame.color="black",vertex.size=12,vertex.label.cex=0.6, vertex.label.cex=0.6,vertex.label.color="black") - This line plots the network using the assigned vertex colors and various vertex and label settings.

legend("bottomleft",legend=c("Module 1","Module 2", "Module 3", "Module 4"),col=color_value, bty="n",fill=color_value,border=color_value) - This line adds a legend to the plot, showing the mapping between the module colors and their names. The bty, fill, and border arguments control the appearance of the legend box.
