However, I am unable to import the Openings project file from the Root Directory (figure 8-38 in the book). </p> <p>When I select the root directory, where the chapter 8 code exists, nothing shows up in the Projects window.

I've been under the weather the past week. I'm having trouble reproducing your bug. Can you provide the full code that you're trying? The only thing different I see is that you used <code>costco</code> singular to name your dataframe, whereas in the book it's plural. But this shouldn't be a problem since you said the symbols() function works when you don't use the <code>add</code> argument. </p> http://forums.flowingdata.com/topic/questions-and-comments-arising-from-visualize-this#post-2272 Thu, 21 Jul 2011 08:53:09 +0000 goblin63 2272@http://forums.flowingdata.com/ <p>@tyson</p> <p>That was exactly the problem.

If so that would mean you get your first value, write it to the file and then close the file. The next time the program runs through the loop (with the second value) it tries to write to a file that is already closed.</p> <p>Paste your code into pastie.org or something similar and give us the link. </p> http://forums.flowingdata.com/topic/questions-and-comments-arising-from-visualize-this#post-2267 Wed, 20 Jul 2011 09:47:16 +0000 goblin63 2267@http://forums.flowingdata.com/ <p>Hi Nathan, </p> <p>I'm a long time fan of the site but a complete newbie to both programming and visualization so I thought your book would be a good place to begin to learn about both of these. I've read it through already and have to say I found it great and can't wait to hopefully work my way through all the examples, however I am having a problem with some of the programming in chapter 2. (Sorry, I'm a complete beginner.)</p> <p>I've worked through and entered all of the code on pages 34 and 35 a number of times and the program runs correctly to start with. It can always find a value for the temperature on the first date. However when it tries to input a value for the second date it always halts and appears with an error message</p> <p>Traceback (most recent call last):<br /> File "C:\Coding\get-weather-data.py", line 34, in &lt;module&gt;<br /> f.write(timestamp + ',' +dayTemp + '\n')<br /> ValueError: I\O operation on closed file</p> <p>I've tried it with the file wunder-data.txt both open and closed and the same message appears for both. I'm working in Python 2.7. </p> <p>Is there any help you can provide on where I've went wrong?</p> <p>Thanks </p> http://forums.flowingdata.com/topic/questions-and-comments-arising-from-visualize-this#post-2265 Sat, 16 Jul 2011 09:49:04 +0000 mattsigal 2265@http://forums.flowingdata.com/ <p>Cool :) That is what I did too.</p> <p>I'm now on the mapping chapter and run into a small R issue (within RStudio and plain ol' R). Here is the code I'm running:<br /> library(maps)<br /> map(database="state")<br /> symbols(costco$Longitude, costco$Latitude, circles=rep(1, length(costco$Longitude)), inches=.05, add=TRUE)</p> <p>Here is the weird part: the "map" function works (I get a map of the USA), but the symbols command absolutely refuses to plot points on it! If I change add to FALSE, then I get a simple scatterplot of the coordinates, so I know those are OK but R is simply refusing to plot the symbols on the map.

Unfortunately, the function in R doesn't have a scaling argument. The good news, however, is that you can see the code for all functions just by typing the name of the function, so if you're feeling adventurous, you can write a modified version as you see fit.</p> <p>If you want to select all the borders at once, you can try selecting one border in Illustrator and then in do Select &gt; Same &gt; Stroke Color (or any of the other options available) </p>
