Comment on Benford’s Law and fraud in the Russian election by richierocks

Agreed, and Ben’s original article says as much. It might be interesting to rerun the analysis with numbers converted to base 5, say, in order to increase the number of orders of magnitude.

Of course, we shouldn’t really expect Benford’s Law to find anything untoward, since sitting down and making up numbers for election results is less likely than ballot stuffing, or intimidating people who would have voted for the opposition, or gerrymandering, or many other ways of rigging an election.

I think that the data don’t follow the distribution of Benford’s law because the numbers generated by this election don’t span several orders of magnitude. Data aggregated for regions follow Benford’s law. I tested the hypothesis with Italian data aggregated for sections and for municipalities and results are similar to Russian’s.

Tried to create an instant GUI using the following structure from your original post of a few months ago. What is the variableType question asking for? thanks, Paul

Well spotted, thanks. Glad you enjoyed the post.

Same problem with Deducer anyway, here :
addComponent(win, btn_calc, 501, 1000, 601, 1, rightType = “REL”)

should be

addComponent(win, btnCalc, 501, 1000, 601, 1, rightType = “REL”)

Just a small bug, probably due to your change from under_casing to camelCase :
in the end of the gWidgets code, it should be :
frmResults <- gframe("results", container = win)
lblP <- glabel(labelP, container = frmResults)
txtP <- gedit(container = frmResults)

instead of the current :
frmResults <- gframe("results", container = win)
lblP <- glabel(labelP, container = frm_results)
txtP <- gedit(container = frm_results)

Thanks for your post anyway, never had the courage to find for those GUI tools, you just made me discover 2 of those

Comment on Exploring the functions in a package by richierocks

Yes. unknownR is very useful, though maybe for a different use case. That’s more about learning R, whereas as lsp is about “I’m sure utils had a function for getting 8 character DOS names, but I can’t remember what it was called.” So you type lsp(utils), and a quick perusal of the results reveals shortPathNames.

Yeah, autocompletion is great, and I use that as well. The R GUI autocompletion only lists the first 10 or so results, so I find it’s better for completion than discovery (unless you know the first few characters of what you are looking for).

Also, autocompletion varies between development environments. I mostly use eclipse these days, and it doesn’t limit completions to a particular package, even if you explcitily type ::.
