How to format describeBy table in R?
<p>I have this data set:</p>

<pre><code>Defects.I    Defects.D       Treatment
    1           2               A
    1           3               B
</code></pre>

<p>And I'm trying to do a descriptive statistics for defects detected and isolated, grouped per treatment.
After searching for a while I found a nice function on the <code>psych</code> library called describeBy().
With the following code:</p>

<pre><code>describeBy(myData[1:2],myData$Treatment) 
</code></pre>

<p>I got this output:</p>

<pre><code>Treatment A        
                  Mean.   Median.    Trimed.
    Defects.I       x        x          x
    Defects.D       x        x          x

Treatment B        
                  Mean.   Median.    Trimed.
    Defects.I       x        x          x
    Defects.D       x        x          x
</code></pre>

<p>But in reality I was looking for something like</p>

<pre><code>                  Mean.   Median.    Trimed.
                  A  B     A  B       A  B
    Defects.I     x  x     x  x       x  x 
    Defects.D     x  x     x  x       x  x
</code></pre>

<p>Data</p>

<pre><code>myData &lt;- structure(list(Defects.I = c(1L, 1L), Defects.D = 2:3, Treatment = c("A", 
"B")), .Names = c("Defects.I", "Defects.D", "Treatment"), class = "data.frame", row.names = c(NA, 
-2L))
</code></pre>
