Some people have indicated that they might want to try their hand and write a macro facility for R, at some time in the future. (There are some parts of the R internals that would benefit from such a facility too).

Meanwhile, update() is your friend.

mdl <- lm(y1-y2 ~ x1+x2+x3,....)
summary(mdl)
summary(update(mdl, y3 - y4 ~ .))
 ...etc...
