    <p>I am implementing a solution to the Traveling Salesman Problem (TSP) in R (simulated Annealing) and I want to output the current best path periodically. I have searched quite a bit for how to output plots during a <code>for</code> loop and have thus far failed. </p> <p>I use RStudio, and want to see the graphs as they are generated. If you have ever watched TSP solvers do their thing, you will understand how cool it is to watch. Here is a sample of the graphics output I want to see <a href="http://www.staff.science.uu.nl/~beuke106/anneal/anneal.html" rel="noreferrer">http://www.staff.science.uu.nl/~beuke106/anneal/anneal.html</a></p> <p>I don't think that the memory usage will be a problem (during about 500,000 iterations, I am only expecting 50-100 plots). Here is a sample function, where we would expect to see 10 different plots during the time the function runs:</p> <pre><code>Plotz &lt;- function(iter = 1000000, interval = 100000) { x &lt;- 1:10 for(i in 1:iter){ y &lt;- runif(10) if(i %% interval == 0) { plot(x, y) } } return(c(x, y)) } Plotz() </code></pre> <p>When I run this, all I see is the final plot produced (in RStudio). How can I see the plots as they're generated?</p> <p>Also: I am on Ubuntu (whatever the newest stable release is). Don't know if that is relevant.</p> <p>Thank you everyone in advance.</p> <p>EDIT: Per Captain Murphy's suggestion, I tried running this in the Linux terminal, and the graphics appeared. I still think the question of "How to do this in RStudio?" Is still relevant, however. It's such a good program, so maybe someone has an idea of what could be done to get this to work?</p> <p>EDIT2: As Thilo stated, this is a known bug in Rstudio. If anyone has any other ideas to solve this without the software itself being fixed, then there is still something to discuss. Otherwise, consider this question solved.</p>

    1. COTry your code in the standard R console (not R studio). The iterative plots seems to appear for me, not just one at the end.

    2. COI don't know if you have seen that, but there are back and forth arrows in the plot panel in RStudio which are actually a great way for you to loop through the generated plots (I didn't notice them for a while). Of course you don't see the plots as they are generated, but after that you can loop through those plots as often as you want.

    3. COI do not have a full answer for you, but maybe some information: It seems this is (was?) a bug in RStudio in 2011. See http://support.rstudio.org/help/discussions/suggestions/214-plots-should-update-in-real-time-osx

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.
