Examples
litters.lm <- lm(brainwt ~ bodywt + lsize, data = litters)
press(litters.lm)
litters.lm0 <- lm(brainwt ~ bodywt + lsize -1, data=litters)
press(litters.lm0) # no intercept
litters.lm1 <- lm(brainwt ~ bodywt, data=litters)
press(litters.lm1) # bodywt only
litters.lm2 <- lm(brainwt ~ bodywt + lsize + lsize:bodywt, data=litters)
press(litters.lm2) # include an interaction term
