Create adjacency matrices from 'graph6', 'sparse6', or 'digraph6' symbols
Source:R/adjacency_from_text.R
adjacency_from_text.RdCreate adjacency matrices from 'graph6', 'sparse6', or 'digraph6' symbols
Details
If object contains 'sparse6' symbols, which are in fact encoded
edgelists, the function will return corresponding adjacency matrices
creating temporary igraph objects internally.
Examples
# Graph6 symbols
sampleg6
#> [1] "CR" "CJ" "CN" "F_?xo" "F@h^_" "F@Miw" "Hr\\~~~~"
#> [8] "H}u|z|~" "Ht\\~~z~"
