QueryNode {rPDBapi} | R Documentation |
Create a Query Node for RCSB PDB Searches
Description
The 'QueryNode' function constructs a query node, which can be either a terminal node (for a simple query) or a grouped node (for complex queries). This function is crucial for structuring queries that will be sent to the RCSB PDB search system.
Usage
QueryNode(search_operator, logical_operator = NULL)
Arguments
search_operator |
A search operator or group object. This defines the criteria for the search. |
logical_operator |
A string specifying the logical operator to combine multiple queries. Default is 'NULL'. This is used only if the search_operator is a group. |
Value
A list representing the query node, ready to be included in a larger query structure.
Examples
node <- QueryNode(search_operator = DefaultOperator("some_value"))
