rbind_to_nodes_info

Updates the node information regarding an R expression.

A customisable set of tools for assessing and grading
R or R-markdown scripts from students. It allows for checking correctness
of code output, runtime statistics and static code analysis. The latter
feature is made possible by representing R expressions using a tree
structure.
