Depending upon how much memory you need to conserve and what else you may need to do with the model object:

  1. lm(YourFormula, data = YourData, model = FALSE)

'model = FALSE' will result in the model frame not being retained.

2. lm(YourFormula, data = YourData, model = FALSE, x = FALSE)

'x = FALSE' will result in the model matrix not being retained.

See ?lm for more information.
