Alternatively, if you don't care about the tabular nature of the
coefficients table, you can just do:
mdl <- lm(Sepal.Width ~ Sepal.Length, data=iris)
That is, use capture.output on the print method and write that out. For
this example, the file would look like
"3" "lm(formula = Sepal.Width ~ Sepal.Length, data = iris)"
"6" " (Intercept) Sepal.Length "
"7" " 3.41895 -0.06188 "
