OptionaladThis may contain additional elements that were part of the original R code, but are not part of the normalized R-ast. This allows inline-comments!
OptionalfileThe file in which the respective node is located
OptionalfullSimilar to Source.fullRange this contains the complete R lexeme of the given element.
OptionalfullThe range is different from the assigned Location as it refers to the complete source range covered by the given element.
As an example for the difference, consider a for loop, the location of `for` will be just the three characters, but the *range* will be everything including the loop body.
Will be used to reconstruct the source of the given element in the R-ast. This will not be part of most comparisons as it is mainly of interest to the reconstruction of R code.
