Artus scored with a superb 30-yard effort that earned the praise of both managers to give the Robins a point.
Yates said: "It was a fantastic goal and I thought it was going to give us the spark we needed to go on and win the game.
"I am frustrated that we didn't win the match convincingly because I was really happy with the performance.
"I thought we were outstanding and the only thing I can be unhappy with is that we didn't finish Morecambe off after Frankie had scored.
"We gave away a bad goal and that was frustrating because we had talked about the danger of Stewart Drummond coming in late and we didn't deal with that."
