This dataset covers a food-borne outbreak of Salmonella Enteritidis PT59
investigated by Public Health England. The data includes a distribution
network, and genetic clusters of bacteria isolated in contaminated
patients. The data is anonymised: identifiers of the food distribution
network have been hashed. The object s_enteritidis_pt59 is a list
containing:
s_enteritidis_pt59An object of class list of length 2.
$graph: a data.frame containing with two columns
from and to specifying (directed) edges of the food
distribution network, alongside reported cases (terminal branches, or 'tips').
$cluster: a factor indicating the genetic cluster of
