    <p>I'm creating a map using the maps library and ggplot's geom_polygon. I'd simply like to change the default blue, red, purple colour scheme to something else. I'm extremely new to ggplot so please forgive if I'm just not using the right data types. Here's what the data I'm using looks like:</p> <pre><code>&gt; head(m) region long lat group order subregion Group.1 debt.to.income.ratio.mean ratio total 17 alabama -87.46201 30.38968 1 1 &lt;NA&gt; alabama 12.4059 20.51282 39 18 alabama -87.48493 30.37249 1 2 &lt;NA&gt; alabama 12.4059 20.51282 39 19 alabama -87.52503 30.37249 1 3 &lt;NA&gt; alabama 12.4059 20.51282 39 20 alabama -87.53076 30.33239 1 4 &lt;NA&gt; alabama 12.4059 20.51282 39 21 alabama -87.57087 30.32665 1 5 &lt;NA&gt; alabama 12.4059 20.51282 39 22 alabama -87.58806 30.32665 1 6 &lt;NA&gt; alabama 12.4059 20.51282 39 &gt; head(v) Group.1 debt.to.income.ratio.mean ratio region total alabama alabama 12.40590 20.51282 alabama 39 alaska alaska 11.05333 33.33333 alaska 6 arizona arizona 11.62867 25.55556 arizona 90 arkansas arkansas 11.90300 5.00000 arkansas 20 california california 11.00183 32.59587 california 678 colorado colorado 11.55424 30.43478 colorado 92 </code></pre> <p>Here's the code:</p> <pre><code>library(ggplot2) library(maps) states &lt;- map_data("state") m &lt;- merge(states, v, by="region") m &lt;- m[order(m$order),] p&lt;-qplot(long, lat, data=m, group=group, fill=ratio, geom="polygon") </code></pre> <p>I've tried the below and more:</p> <pre><code>cols &lt;- c("8" = "red","4" = "blue","6" = "darkgreen", "10" = "orange") p + scale_colour_manual(values = cols) p + scale_colour_brewer(palette="Set1") p + scale_color_manual(values=c("#CC6666", "#9999CC")) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
