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()
