Standard deck of 52 playing cards in curated data?


I am not sure how to find out what all is included as curated data. For example, are the individual images of each of the 52 cards in a standard deck of playing cards included?



If not, is there a way to systematically access these from web images?



Answer



You can get some nice vector playing cards from this site, licensed under GNU LGPL (read more here). Download this folder to your computer and then try the following:


(* replace with your download dir *)
files = Flatten@With[{dir = "~/Downloads/Chrome/mma/SVG_and_EPS_Vector_Playing_Cards_Version_1.3/EPS_Vector_Playing_Cards_Version_1.3/52-Individual-Vector-Playing-Cards-1.2_(EPS-Format)/"},
FileNames["*.eps", dir, 2]];

Clear@CardData
SetAttributes[CardData, Listable]
StringCases[Last@FileNameSplit@#, card__ ~~ ".eps" :>

(CardData[card] = ImageCrop@Import@#)] & /@ files;

You can then use this like any other curated data:


GraphicsRow[CardData@{"2C", "KH", "AS", "QD", "JC"}]




Random hand generator:


You can extend this further and also create a random hand generator using Mathematica as follows:


deck = Flatten@With[

{
ranks = CharacterRange["2", "9"] ~Join~ {"10", "J", "Q", "K", "A"},
suits = {"C", "S", "H", "D"}
},
Outer[StringJoin, ranks, suits]
];
dealHand[n_Integer] /; 1 ≤ n ≤ 52 := CardData@RandomSample[deck, n]

Use this to deal a hand as dealHand[5], for instance. You'll have to modify this a bit to deal randomly and exhaust the deck at the same time (as you would in a game). There was a question on this previously on this site and I gave an answer based on Internal`Bag[] that will be useful here (along with some of the other answers there).

plotting - How to draw lines between specified dots on ListPlot?

I would like to create a plot where I have unconnected dots and some connected. So far, I have figured out how to draw the dots. My code is the following: ListPlot[{{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4,13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full] I have thought using ListLinePlot command, but I don't know how to specify to the command to draw only selected lines between the dots. Do have any suggestions/hints on how to do that? Thank you. Answer One possibility would be to use Epilog with Line : ListPlot[ {{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4, 13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full, Epilog -> { Line[ ...

dynamic - How can I make a clickable ArrayPlot that returns input?

I would like to create a dynamic ArrayPlot so that the rectangles, when clicked, provide the input. Can I use ArrayPlot for this? Or is there something else I should have to use? Answer ArrayPlot is much more than just a simple array like Grid : it represents a ranged 2D dataset, and its visualization can be finetuned by options like DataReversed and DataRange . These features make it quite complicated to reproduce the same layout and order with Grid . Here I offer AnnotatedArrayPlot which comes in handy when your dataset is more than just a flat 2D array. The dynamic interface allows highlighting individual cells and possibly interacting with them. AnnotatedArrayPlot works the same way as ArrayPlot and accepts the same options plus Enabled , HighlightCoordinates , HighlightStyle and HighlightElementFunction . data = {{Missing["HasSomeMoreData"], GrayLevel[ 1], {RGBColor[0, 1, 1], RGBColor[0, 0, 1], GrayLevel[1]}, RGBColor[0, 1, 0]}, {GrayLevel[0], GrayLevel...

Is there a way to do conditional matrix loop using 'continue'

I have the following: n = 3; m = 5; ww = RandomReal[{0, 0.1}, {n, n}]; uu = RandomReal[{0, 1}, {m, n}]; pp = RandomReal[{0, 1}, {n, n}]; ss = RandomInteger[{0, 5}, {m, n}]; Grid[{{"ww", "uu", "pp", "ss"}, {ww // TableForm, uu // TableForm, pp // TableForm, ss // TableForm}}, Spacings -> {5, 2}, Dividers -> All] where I would like to look at every element of matrix ss and produce a matrix tt , with zeroes at the locations in ss which have zeroes, and in all other positions do the following: tt = (-1/Subscript[ww, m]) Log[(1 - uu)/(Subscript[pp, m - 1])], where Subscript[ww, m] is the value at index of ww matrix and where Subscript[pp, m - 1] is the value at index-1 of pp matrix. So for example if the first value ever read from matrix ss happens to be 2, then value taken from matrix ww would be from the row 2, but from pp would be from row 1. Also how to tell difference between a 0 as a valid value from within the matrix elemen...
