Great question. The trick would be to use order() as an index vector<br class="gmail_msg">
inside square brackets. So if my.data is a acs object and you want to<br class="gmail_msg">
plot the first column, an unsorted plot would be:<br class="gmail_msg">
<br class="gmail_msg">
> plot(my.data[,1])<br class="gmail_msg">
<br class="gmail_msg">
and a sorted plot might be<br class="gmail_msg">
<br class="gmail_msg">
> plot(my.data[order(estimate(my.data[,1])),1])<br class="gmail_msg">
<br class="gmail_msg">
should do the trick.<br class="gmail_msg">

If you're doing a bunch of this sort of thing, or maybe if you want to<br class="gmail_msg">
plot one column based on the order of another (say, the percentage of<br class="gmail_msg">
commuters in a tract, by order of the median HH income of the tracts),<br class="gmail_msg">
you could save the indices:<br class="gmail_msg">
<br class="gmail_msg">
> my.index=order(estimate(my.data[,1]))<br class="gmail_msg">
> plot(my.data[my.index, 1])<br class="gmail_msg">
