Convert adjacency list to an adjacency matrix

adjacencyList2Matrix(lt, square = FALSE)

Arguments

lt	A data frame which contains adjacency list.
square	Should the returned matrix be a square matrix?

Examples

set.seed(123)
df = data.frame(from = sample(letters, 10, replace = TRUE),
                to = sample(letters, 10, replace = TRUE),
                value = 1:10)
adjacencyList2Matrix(df)
