Yes it very simple to make it 10000 x faster when testing a 12 million strings list ;) The simplest solution is maybe to build first an optimized ([`Dispatch`][1]) list of rules ([`Rule`][2]) which associates the strings with their position in the...
Maybe: 1/ if you want only True or False answers to your tests then wrap Simplify with TrueQ TrueQ[Simplify[(a - b) + c == (a - c) + b]] > `False` You could also use directly SameQ (===) instead of Equal (==) (a - b) + c === (a...
Starting from `member` (your original list): dt=GroupBy[member, First->Rest, Map[AssociationThread[{"year","students"}->#]&,#]&] or even a little bit shorter using the operator form of `Map` dt=GroupBy[member, First->Rest,...
Here it goes ! &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/920d93a1-d171-4971-8417-9fefa5a75e62
Got the same result (OS X) than you but this was fixed just by setting the option `PlayRange->All` in `Play`. By default this option is set to `Automatic` and according to the docs it says "outlying levels are dropped". This is why you observe that...
Try `ComplexExpand`.
What you need seems to be a combination of `PlotRange->All`, `ViewAngle` and `ViewVector`. For example: Manipulate[ Framed[ Graphics3D[{Sphere[{-sep, 0, 0}], Sphere[{0, 0, 0}], Sphere[{sep, 0, 0}]}, Axes -> False,...
Probably, the missing data is tagged with additional "reason" (look at the docs for the `Missing` syntax). Maybe this example will help: ds = Dataset[{ 1, "b" -> 11|>, 2, "b" -> Missing["somereason"]|>, 3, "b" -> Missing[]|>}] ...
You have to be very careful here with this approach, one might think that the time scale is linear here which is not, because your data are not regularly sampled. For example, as you can see the distances (30th of March - 10th of April) and (10th of...
Yes, I got the same problem with v11.0.1. This workaround seems to work : DiscretizeGraphics@ Thread@CountryData["France", {"Polygon", "Mercator"}] ![enter image description here][1] [1]:...
