How to represent socketed components in schematic
Although I haven't done it, here's how I would do it.

Create a schematic component for the machined pin socket (DIP-8, -14, 16, SIP, etc).  Make each pin its own sub-component: J107-1, J107-2, ..., J107-16. This is not unlike U2A and U2B for a dual OpAmp.  (Alternatively, you could make each pair of pins a sub-component: 1 and 16, 2 and 15. That would be somewhat less flexible, but fewer parts to keep track of.)

Make the actual resistor and capacitor components such that they don't have pads.  Specific details of how to achieve this would depend on the schematic and layout software which you are using.  Some software have a setting that allows to exclude a component from layout.  Other software doesn't have a setting like that (OrCAD for instance).  But you can create a dummy component without pads.  The a designator for the plugged in component may come handy on the PCB.



Here's what it would look like.  R42 is plugged into pins 2 and 15 of J107.  The latter is a DIP-16 socket.
