How can we simulate Bridge Rectifier on Spice?

I did with four diodes as practical but got 'DC sine wave' as an output haha What kind of simulation it is? How to simulate it? I used 7805 to get pure DC without such sine (or ripple) here but got same sine.

You need to move the ground to the bottom of R, if you wish to see the voltage there.

Either that or use waveform arithmetic to plot the voltage across R. Plot [V(top-node) - V(bottom-node)] where top-node and bottom-node are the node names on either side of R in your circuit.
