Build a directed graph of code changes based on a Klass classification

Build a directed graph of code changes based on a Klass classification

Usage

klass_graph(classification, date = NULL)

Arguments

classification

The ID of the desired classification.

date

The date which the edges of the graph should be directed towards.

Defaults to the current year plus one, which ensures the graph is directed to the most recent codes.

Value

An igraph object with the vertexes representing codes, and edges representing changes between codes. The direction of the edges represent changes towards the date specified in date.

Examples

library(klassR)

# Build a graph directed towards the most recent codes
if (FALSE) { # \dontrun{
klass_131 <- klass_graph(131)
} # }

# Build a graph directed towards valid codes in 2020.
if (FALSE) { # \dontrun{
klass_131_2020 <- klass_graph(131, "2020-01-01")
} # }
