I would like to draw a set of points that are equally spaced in a 2-D
grid. Then I would like to draw lines that illustrate different
directed paths through subsets of points. Imagine that the points
correspond to booths in a conference center, and I want to show the
various paths people took to vi
Thanks for the replies! The answer is that barplot() returns the x
coordinates of the bars.

How can I write text inside a bar of a barplot? I tried using text(), but I
am only able to specify the numeric y-coordinate. The different columns of
my barplot correspond to factors and not numbers, so I don't know how to
access the horizontal positions of the bars. I tried fiddling with differen
Thanks Jim! I followed the instructions in the FAQ and wrapped print()
around my function calls. The images are now properly generated.

I am encountering problems using the png() function to save around 20 charts
to separate files.
My script is conceptually structured as follows:
###
png("Image %03d.png")
# the following are calls to user-defined functions I wrote that call plot,
barchart, etc. with special arguments.

When I use barchart (with default formatting options), I get bars whose
lengths/heights are not proportional to their value. For example:

Many of the values in this chart are 1; however, because the blue bars
extend to the left of the "0" tick mark, those

Let's say I have data in the following schema that describes the number of
purchases a company has received from each County in the US:
State | County | Purchases

NJ | Mercer | 550
CA | Orange | 23
