    print(x$call)
    cat("\nResiduals:\n")
    print(x$residSum)
    cat("\n")

    printCoefmat(x$coefficients, P.values=TRUE, has.Pvalue=TRUE)
    digits <- max(3, getOption("digits") - 3)
    cat("\nResidual standard error: ", formatC(x$sigma, digits=digits), " on ",
        formatC(x$df), " degrees of freedom\n", sep="")
    cat("Multiple R-squared: ", formatC(x$r.squared, digits=digits),
        ",\tAdjusted R-squared: ",formatC(x$adj.r.squared, digits=digits),
        "\n", sep="")
    invisible(x)
}
