From an adjacency matrix, extracts two data.frames/tibbles

Links. columns : from, to, with, weight

Nodes. columns : name, title. name corresponds to the names used in 'from' and 'to'

abs_threshold = TRUE, filter_nodes = TRUE)
``` |

`adjacency_matrix` |
: a matrix of size n x n, each element being a number explaining the relationship e.g. coefficient, information between two variables given in the column and row names /!\ As this code is to draw undirected graphs, only the lower triangular part of adjacency matrix is used to extract the information. |

`legend` |
: a data frame of columns in order : 1) name, str : name of the node in the adjacency matrix, e.g. CRUDSAL_cat 2) title, str : name of the node, e.g. Raw vegetables 3) family, factor : (optional) the family the node belongs to, e.g. Vegetables |

`threshold` |
numeric) : a number defining the minimal threshold. If the weights are less than this threshold, they will be set to 0. |

`abs_threshold` |
(bool) : should the threshold keep negative values,
e.g. if |

`filter_nodes` |
(bool) : should the variables not in the adjacency
matrix be displayed on the graph? Default is TRUE
CAREFUL : if set to |

A list of two data frames : links and nodes.
