Formatted text output

How does one write formatted, say "C style", output to a text file.  I 
want something like "y=mx+b" for my linear regressions but with m and b 
derived from the fit objects.  Also, how does one go about extracting 
just the slope or intercept from such an object. - Greg

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()
