Removing non-numeric argument to binary operator Error
<p>I am extremely new to R (Day 2). I am putting together a bargraph but am constantly getting the "non-numeric argument to binary operator. Below is all of the code I have written thus far. Any suggestions? I understand that is the (+) error but am unsure of how to correct it and still receive my graph.</p>

<p>I have attempted to remove the <code>guides(fill=FALSE)</code> but then I do not get a graph just this: </p>

<pre><code>plot &lt;- ggplot(data=sumcult5ml, aes(x=reorder(cultivar,eggs5ml, y=eggs5ml)))

geom_bar(aes(fill="sumcult5ml", TRUE),stat="bin", width=.5)

mapping: x = TRUE, fill = sumcult5ml 

geom_bar: width = 0.5, na.rm = FALSE

stat_bin: width = 0.5, na.rm = FALSE

position_stack
</code></pre>

<p>Code:</p>

<pre><code>plot &lt;- ggplot(data=sumcult5ml, aes(x=reorder(cultivar,eggs5ml, y=eggs5ml))) 

geom_bar(aes(fill="sumcult5ml", TRUE),stat="bin", width=.5) + guides(fill=FALSE)
</code></pre>

<p>Error:</p>

<pre><code>&gt; plot &lt;- ggplot(data=sumcult5ml, aes(x=reorder(cultivar,eggs5ml, y=eggs5ml)))

&gt; geom_bar(aes(fill="sumcult5ml", TRUE),stat="bin", width=.5) + guides(fill=FALSE)

Error in geom_bar(aes(fill = "sumcult5ml", TRUE), stat = "bin", width = 0.5) +  : 
  non-numeric argument to binary operator
</code></pre>

<p>Thank you for any tips!!</p>
