How to make a point plot with factors in the X axis in R?
<p>I'm trying to get the a plot for demonstrative purpose (I know it my not make statistical sense, but it's precisely to discuss that). The plot must have factors in the X axis (Data$Site) and a certain value in the Y axis(Data$Count). For each "Site" a point must be appear with a size equal to the Data$Mean. My current code and it's results are as follows:</p>

<pre><code>&gt; is.factor(Data$Site)
TRUE
&gt; Data$Site
[1] Creek  Shade  Valley
Levels: Creek Shade Valley

&gt; Data$Count
[1] 2.1 3.0 8.5

&gt; Data$Mean
[1] 1.456 2.3445 1.345

plot(Data$Site, Data$Count, type = "p", pch=15, cex=Data$Mean)
</code></pre>

<p>Obviously, I don't want lines. I want points that are of the size of Data$Mean. Is there quick and neat a way to do it in R? I have reviewed other packages like lattice and ggplot to not avail.</p>
