Following the __posting guide__ should have gotten you through this. viz.
??format ## leads to sprintf
?lm ## See Also coef
?coef ## "Extract Model Coefficients"
??file ## leads to sink
?sink ## "Send R Output to a File"
e.g.
> coefs <- coef( lm(rnorm(10)~I(1:10)) ) ## for example
> sprintf( "y = %5.2fx%+5.2f", coefs[2], coefs[1] )
[1] "y = -0.08x+0.50"
> sink("myFile.txt")
> sprintf( "y = %5.2fx%+5.2f", coefs[2], coefs[1] )
> sink()
