Old Nick said:In eagle if you just name the nets.
Click on the resistor icon with R2 highlighted (and then the wire/net) and give your net a name. If you give subsequent nets the same name you will be prompted to join the nets.
To display the names of the nets on your schematic click on the label icon (picture of a net with ABC above it) and then on the net you want to display the name of. The frames library has ports of varying size you can use for neatness.
