(This article was first published on <strong><a href="http://www.win-vector.com/blog/2018/11/r-tip-make-your-results-clear-with-sigr/"> R – Win-Vector Blog</a></strong>, and kindly contributed to <a rel="nofollow" href="https://www.r-bloggers.com/">R-bloggers)</a> </div>
<p><a rel="nofollow" href="https://www.r-project.org/" target="_blank">R</a> is designed to make working with statistical models fast, succinct, and reliable.</p>
<p>For instance building a model is a one-liner:</p>
<pre>
model &lt;- lm(Petal.Length ~ Sepal.Length, data = iris)
</pre>
<p>And producing a detailed diagnostic summary of the model is also a one-liner:</p>
<pre>
summary(model)

# Call:
# lm(formula = Petal.Length ~ Sepal.Length, data = iris)
# 
# Residuals:
#      Min       1Q   Median       3Q      Max 
# -2.47747 -0.59072 -0.00668  0.60484  2.49512 
# 
# Coefficients:
#              Estimate Std. Error t value Pr(>|t|)    
# (Intercept)  -7.10144    0.50666  -14.02   &lt;2e-16 ***
# Sepal.Length  1.85843    0.08586   21.65   &lt;2e-16 ***
# ---
# Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1
# 
# Residual standard error: 0.8678 on 148 degrees of freedom
# Multiple R-squared:   0.76,   Adjusted R-squared:  0.7583 
# F-statistic: 468.6 on 1 and 148 DF,  p-value: &lt; 2.2e-16
</pre>
<p>However, useful as the above is: it isn’t exactly presentation ready. To formally report the R-squared of our model we would have to cut and paste this information from the summary. That is a needlessly laborious and possibly error-prone step.</p>
<p>With the <a rel="nofollow" href="https://winvector.github.io/sigr/" target="_blank"><code>sigr</code></a> package this can be made much easier:</p>
<pre>
library(&quot;sigr&quot;)
Rsquared &lt;- wrapFTest(model)
print(Rsquared)

# [1] &quot;F Test summary: (R2=0.76, F(1,148)=468.6, p&lt;1e-05).&quot;
</pre>
<p>And this formal summary can be directly rendered into many formats (Latex, html, markdown, and ascii).</p>
<pre>
render(Rsquared, format=&quot;html&quot;)
</pre>
<p><b>F Test</b> summary: (<i>R<sup>2</sup></i>=0.76, <i>F</i>(1,148)=468.6, <i>p</i>&lt;1e-05).</p>
<p><a rel="nofollow" href="https://winvector.github.io/sigr/" target="_blank"><code>sigr</code></a> can help make your publication workflow much easier and more repeatable/reliable.</p>
