## S3 method for class 'ASTNode'
x == y

## S3 method for class 'ASTNode'
x != y

x, y	(ASTNode) The objects to compare.

Details

These functions traverse the given RStatic objects to check that their children are also equal. Except for Symbol names and Literal values, fields that do not contain children are ignored.

Value

A logical scalar indicating the result of the comparison.
