Display content of input script in 'Cytoscape'

Description

This function allows the user to represent the content of a given script in 'Cytoscape' (<https://cytoscape.org/>). Therefore it requires to have a functioning version of 'Cytoscape' 3.6.1 or greater.

Each variable is represented as a node and edges represent commands that call the variable. Functions can also be represented.

A color code is associated to each nodes:

- white: intermediate variables (that are created and used to create new ones),

- pink: subsets of a variable (ex: var2 in var1$var2),

- green: final variables (that are created and not used afterwards),

- red: warnings, message and stop functions,

- yellow: if, else if, else and ifelse functions,

- orange: for, foreach and while functions,

- blue: *print, cat or other functions at beginning of line,

- gray: packages import and session info (wd)

Edge color reports the sequence of command on a blue scale (light: early in the script -to- dark: late in the script) Node color code extend to edges in case of loops or tests (orange and yellow)

Edges of type sinewave represent the connection between a node and itself when used as an indice. Edges of type dots represent the commands within a if, else, else if, ifelse or loop condition.

User created functions are represented and pooled as a group, collapsed and extracted to a subnetwork to avoid latency.
