This package provides an R implementation of the netinf algorithm created by @gomez2010inferring (see here for more information and the original C++ implementation). Given a set of events that spread between a set of nodes the algorithm infers the most likely stable diffusion network that is underlying the diffusion process.
The package can be installed from CRAN:
The latest development version can be installed from github:
To get started, get your data into the cascades
format required by the netinf
function:
library(NetworkInference)
# Simulate random cascade data
df <- simulate_rnd_cascades(50, n_node = 20)
# Cast data into `cascades` object
## From long format
cascades <- as_cascade_long(df)
## From wide format
df_matrix <- as.matrix(cascades) ### Create example matrix
cascades <- as_cascade_wide(df_matrix)
Then fit the model:
origin_node | destination_node | improvement | p_value |
---|---|---|---|
