network.tools

Tools to work with bipartite networks.

Installation

You can install the development version of network.tools from GitHub with:

# install.packages("devtools")
devtools::install_github("Pakillo/network.tools")

Usage

Network visualisation

Visualise bipartite network as heatmap

Binarize the network (make it qualitative):

plot_web_heatmap(web, binarize = TRUE)

The output is a ggplot object that can be further modified:

plot_web_heatmap(web) + 
  ggplot2::labs(title = "A bipartite network")

Data management

Transform interaction data from long to wide format 

head(web)
#>   Plant Animal Visits
#> 1    P1     A1      1
#> 2    P1     A2      0
#> 3    P1     A3      0
#> 4    P1     A4      0
#> 5    P1     A5      2
#> 6    P1     A6      0

#> P4  1  1  1  2  1  1  0  2
#> P1  0  1  0  0  2  1  2  0

Transform interaction data from wide to long format 

mat <- long2wide(web)
wide2long(mat)
