nldoc_network: Create NetLogo procedure network

Description

Create NetLogo procedure network

Usage

nldoc_network(modelfiles)

Arguments

modelfiles

vector of filepaths to model files

Value

network of model procedures (igraph)

Details

Reads model code from the provided model files. The procedure identifies NetLogo procedures and searches for procedure calls within the code. From this data, an igraph network is created and returned. This network can be used to plot the model procedure network and identify model components.

Examples

# NOT RUN {
# List model files (.nls subfiles are also supported)
modelfiles <- c("https://raw.githubusercontent.com/nldoc/nldoc_pg/master/WSP.nlogo",
                "https://raw.githubusercontent.com/nldoc/nldoc_pg/master/WSP.nls")

# Determine the function network:
nw <- nldoc_network(modelfiles)

# Determine communities within the network and plot using Igraph package:
library(igraph)
com <- walktrap.community(nw)
V(nw)$community <- com$membership
rain <- rainbow(14, alpha=.5)
V(nw)$color <- rain[V(nw)$community]

plot(nw,
     edge.arrow.size=.2,
     vertex.label.color="black",
     vertex.label.dist=1,
     vertex.size=5,
     edge.curved=0,
     vertex.label.cex=.5,
     layout=layout_with_fr(nw, niter = 2000))

# Interactive plot using igraph::tkplot
tkplot(nw, layout=layout_with_fr(nw, niter = 2000))
# }
