&gt; And it&#x27;s really hard to beat ggplot.<p>To be honest, matplotlib seems a good contender to me (<a href="http:&#x2F;&#x2F;matplotlib.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;matplotlib.org&#x2F;</a>).<p>Also, what&#x27;s wrong with comparing R to Pandas&#x2F;Numpy ? They can only be used from within Python, right?<p>Edit: just realised from another comment that Pandas&#x2F;Numpy can be accessed from R, too.
