[R] lm() intercept at the end, rather than at the beginning

Try this.  It captures the output of x and sets idx to the line numbers
of the coefficients, rearranging their order in the next line and printing
them out in the line after that.

my.print.summary.lm <- function(x, ...) {
	out <- capture.output(x)
	idx <- seq(grep("Intercept", out), grep("---", out)-1)
	out[idx] <- out[c(idx[-1], idx[1])]
	for(lin in replace(out, idx, out[rev(idx)])) cat(lin, "\n")
z <- summary(lm(conc ~ uptake, CO2))
