Create Decoration's Graphs and Store them in a List

Create undirected graphs for each decoration from nodes, edges and imgs dataframes and store the graphs in a list. The join between these dataframes is done on the two fields site and decor. Graph names refer to imgs$idf.

list_dec(imgs,
           nodes,
           edges)

Arguments

imgs	Dataframe of decorations
nodes	Dataframe of nodes
edges	Dataframe of edges

Value

A list of igraph graphs.

Examples

# Read imgs, nodes and edges dataframes
imgs <- read.table(system.file("extdata", "imgs.csv", package = "iconr"),
                   sep=";", stringsAsFactors = FALSE)
nodes <- read.table(system.file("extdata", "nodes.csv", package = "iconr"),
                    sep=";", stringsAsFactors = FALSE)
edges <- read.table(system.file("extdata", "edges.csv", package = "iconr"),
                    sep=";", stringsAsFactors = FALSE)
# Create the list of graphs
lgrph <- list_dec(imgs, nodes, edges)

# Get the first graph
g <- lgrph[[1]]
