[R] metaprogramming with lm

Say I want to make a multiple regression model with the following expression:

lm(y~x1 + x2 + x3 + ... + x_n,data=mydata)

It gets boring to type in the whole independent variables, in this
case x_i. Is there any simple way to do the metaprogramming for this?
(There are different cases where the names of the independent
variables might sometimes have apparent patterns or not)
