Canadian election graph
Just FYI. I added another poll for EKOS October 3 that was previously missed... I saw you already had data points for October 4 in your graph, and wasn't sure if you might miss it since it's in the past (e.g. if you grab just the newest ones, rather than the whole set) frogg (talk) 17:05, 6 October 2008 (UTC)

First of all thanks a lot for consistently doing this everyday... Just thought I'd point out an apparent error in today's graph... the green points on the graph are 11,12,9 but the data points are 11,12,7. Not sure how that happened... frogg (talk) 02:13, 10 October 2008 (UTC)

Graph
Hi, I would like to know wich software you are using to do nice graph, like the one for the federal election. Thanks! --Riba-- (talk) 13:57, 10 November 2008 (UTC)

Airfoil
Hello Galneweinhaw! On 10 October you added a message at Talk:Airfoil saying ''I'm a bit concerned with the explanation here, but it looks like the issue is contentious. Is there anyone following this article willing to discuss it?'' However, you then deleted it.

Yes, I do follow all discussions on the subjects of airfoils, lift and Bernoulli's principle, and I'm very happy to discuss. You could raise your concerns on any of the Talk pages, or on my User talk page. If you have a concern with any of the explanation in the article let's discuss it and get it sorted it out. I will respond.

I see you are a physics teacher. I am an aeronautical engineer so I have done quite a bit of physics over the years, and I talk the language. Best wishes. Dolphin ( t ) 07:54, 10 October 2010 (UTC)

Opinion polling in the Canadian federal election, 2011
Hey glad to see you are back and that your graph is back, too! Just in time for the critical period of the campaign! - Ahunt (talk) 10:34, 28 April 2011 (UTC)
 * Hey man, gotta chip in too and say that graph is just all kinds of awesome. Good job! -- Natural  R X 02:58, 30 April 2011 (UTC)
 * Very nice plots. Keep-up the good work! Nephron T|C 20:05, 1 May 2011 (UTC)

Opinion polling in the 43rd Canadian federal election
Greetings Galneweinhaw,

Any chance you'd be willing/able to help set up an R-based graph like the nice one you did for the 2015 federal election campaign on the current opinion polling page? Nanos is at it again with the "rolling" polls for which only 1/4 of the sample of each successive poll is independent from the previous poll. Unadjusted, these polls are disproportionately influencing the trend line in the simple 30-day-average graph that's currently up, so it would be nice to set up one of the local regression graphs with weighting of polls by sample size. The challenge will be to tweak the code so that all Nanos polls with a sample size listed as "1000 (1/4)" get weighted as though they have a sample size of 250. Any help you could provide would be greatly appreciated. Cheers, Undermedia (talk) 15:44, 4 April 2017 (UTC)


 * Yes! Heading to France for the Vimy 100th this week, but I'll take a look when I get back in a couple weeks.  I was working on a web-based plot generator so other users could generate similar graphs... but I can't remember where I left it =). galneweinhaw (talk) 22:36, 4 April 2017 (UTC)

2018 Ontario general election opinion polling graph
Hi Galneweinhaw. I'm trying to adapt your R code to produce a graph for the campaign-period polls in the now-underway Ontario election campaign. I think I'm very close to getting it right, but I'm getting the following error which I can't quite seem to decipher: Error in eval(e, x, parent.frame) : object 'colour' not found. I did remove ("#") a few things from the code, namely the stuff relating to displaying the results of the last election, which I don't want to do for this graph; just a straightforward plot showing only the polls released during the campaign period. Your assistance would be appreciated. Is there some way I can share my code with you so you can take a look? Cheers, Undermedia (talk) 15:01, 10 May 2018 (UTC)
 * Can you post your code on github or past it to pastebin so I can take a look? Thanks galneweinhaw (talk) 23:36, 10 May 2018 (UTC)
 * Here you go. Thanks for taking a look! Undermedia (talk) 13:36, 11 May 2018 (UTC)
 * Alright, now that a second poll has been added to the table, I'm no longer getting the eval error, but instead the following: Error in f(..., self = self) : Breaks and labels are different lengths. Sorry, I was really hoping to be able to figure this one out all on my own without having to bother you again, but evidently I'm not quite there yet! Cheers, Undermedia (talk) 13:32, 12 May 2018 (UTC)
 * I've made some progress (it actually outputs a graph now!), but a critical problem is that it seems to somehow still be fetching data from the federal election polling page (party names in the legend and the polls themselves) and I have no idea how/why, but it looks like it might have something to do with the election_polls statement. Undermedia (talk) 17:44, 12 May 2018 (UTC)
 * Lol, sorry to bombard you with all these updates, but I now seem to have the graph working, at least on a rudimentary level. With only 2 polls so far (had to set num_data_points to 2), there's not much going (and no confidence ribbons yet), but I assume it will start looking more interesting as more polls are added. R is still telling me: There were 50 or more warnings (use warnings to see the first 50)—so you might still want to look at my current code in case you can spot anything that seems wildly off. Cheers, Undermedia (talk) 18:25, 12 May 2018 (UTC)
 * No prob! I just sat down to take a look and saw that you figured it out, that's awesome!  Let me know if you have any other problems.  Apologies for the slow replies =) galneweinhaw (talk) 05:05, 13 May 2018 (UTC)
 * Would you mind playing around with it now that a 3rd poll has been added to the table? The plot output and number of warnings vary depending on the value entered for num_data_points: at this point a value of 2 fails to produce the plot altogether; a value of 3 (50+ warnings) works but produces massive confidence ribbons that span the entire height of the plot; a value of 4 (23 warnings) is similar except the ribbons stop at the 2nd poll; values 5–7 produce no confidence ribbons at all; etc. Is this simply happening because there are as of yet very few polls/datapoints in the table?
