Evaluate part of an expression at C level
Hi, I am wondering if the below is possible? Let's assume I have the following expression: 1:10 < 5 Is there a way at the R C API level to only evaluate the 5th element (i.e 5 < 5) instead of evaluating the whole expression and then select the 5th element in the logical vector? Thank you Best regards Morgan [[alternative HTML version deleted]]
