Formatted text output
4 messages · Gregory Propf, David Winsemius, Charles C. Berry
The innards of an object can be revealed with the str function and the coef function should have been a link off the lm page (assuming that was the sort of "fit" you were creating.) For output to files see ?cat

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 [[alternative HTML version deleted]]

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()
