import - Assign the contents of a "Copy" operation programmatically to a variable?


While an earlier question Cut and paste data from a spreadsheet nominally addresses the issue, a year has past since its OP asked it and I hope that others have come across simpler or more direct ways to do this. I think a new solution might interest the community.



I often want to get values (numbers, dates, ...) from a spreadsheet someone has sent me into Mathematica.


Import[...] works fine, but seems a bit cumbersome, when I just want to grab something like a single column or row of values and work with them immediately.


"Copy/Paste" can give one odd results. Set up a short list of numbers in a spreadsheet ...

and copy them into Mathematica:

This seems a bit inconsistent and neither of these gives one a list of the data elements like Import[...].


Note: I use Mac OS X if it makes any difference.



Mr. Wizard supplies a pretty good solution in the original question, which references code for a palette that Szabolcs posted at see page, see Pasting tabular data into notebooks.



I've added a title and minor formatting to the palette:


CreatePalette[
 Column[{Button["TSV", 
    Module[{data, strip}, 
     data = NotebookGet[ClipboardNotebook[]][[1, 1, 1]];
     strip[s_String] := 
      StringReplace[s, RegularExpression["^\\s*(.*?)\\s*$"] -> "$1"];
     strip[e_] := e;
     If[Head[data] === String, 
      NotebookWrite[InputNotebook[], 

       ToBoxes@Map[strip, ImportString[data, "TSV"], {2}]]]], 
    ImageSize -> 85], 
   Button["CSV", 
    Module[{data, strip}, 
     data = NotebookGet[ClipboardNotebook[]][[1, 1, 1]];
     strip[s_String] := 
      StringReplace[s, RegularExpression["^\\s*(.*?)\\s*$"] -> "$1"];
     strip[e_] := e;
     If[Head[data] === String, 
      NotebookWrite[InputNotebook[], 

       ToBoxes@Map[strip, ImportString[data, "CSV"], {2}]]]], 
    ImageSize -> 85], 
   Button["Table", 
    Module[{data}, 
     data = NotebookGet[ClipboardNotebook[]][[1, 1, 1]];
     If[Head[data] === String, 
      NotebookWrite[InputNotebook[], 
       ToBoxes@ImportString[data, "Table"]]]], ImageSize -> 85]}, 
  Alignment -> {Center, Center}], WindowTitle -> "Paste Data", 
 WindowSize -> {85, Fit}]


One can install this by choosing Palettes > Install Palette (from the file menu) then provide the source file, palette name, and installation directory to the Install Mathematica Item dialog, and click Finish.



This works, but it does not have the immediacy that one gets used to when working with Mathematica, so...


Does a simple way exist to assign the contents of a "Copy" operation (from a spread sheet or csv file) programmatically to a variable as a list of elements, which one could immediately press into service?


Given that a clipboard appears to hold copies of content in different formats, an elegant solution might involve a right click to select how one wanted it pasted. Maybe a feature request to Wolfram would do it (eventually:-).



Answer



For Windows users something could perhaps be created using NETLink. For a basic demonstration:


Needs["NETLink`"];
InstallNET[];

LoadNETType["System.Windows.Forms.Clipboard"];

Now copy the data in Excel and evaluate:


ImportString[Clipboard`GetText[], "Table"]
(* {{1}, {2}, {3}, {4}, {5}} *)

plotting - Filling between two spheres in SphericalPlot3D

Manipulate[ SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, Mesh -> None, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], {n, 0, 1}] I cant' seem to be able to make a filling between two spheres. I've already tried the obvious Filling -> {1 -> {2}} but Mathematica doesn't seem to like that option. Is there any easy way around this or ... Answer There is no built-in filling in SphericalPlot3D . One option is to use ParametricPlot3D to draw the surfaces between the two shells: Manipulate[ Show[SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], ParametricPlot3D[{ r {Sin[t] Cos[1.5 Pi], Sin[t] Sin[1.5 Pi], Cos[t]}, r {Sin[t] Cos[0 Pi], Sin[t] Sin[0 Pi], Cos[t]}}, {r, 1, 2 - n}, {t, 0, Pi}, PlotStyle -> Yellow, Mesh -> {2, 15}]], {n, 0, 1}]

plotting - Plot 4D data with color as 4th dimension

I have a list of 4D data (x position, y position, amplitude, wavelength). I want to plot x, y, and amplitude on a 3D plot and have the color of the points correspond to the wavelength. I have seen many examples using functions to define color but my wavelength cannot be expressed by an analytic function. Is there a simple way to do this? Answer Here a another possible way to visualize 4D data: data = Flatten[Table[{x, y, x^2 + y^2, Sin[x - y]}, {x, -Pi, Pi,Pi/10}, {y,-Pi,Pi, Pi/10}], 1]; You can use the function Point along with VertexColors . Now the points are places using the first three elements and the color is determined by the fourth. In this case I used Hue, but you can use whatever you prefer. Graphics3D[ Point[data[[All, 1 ;; 3]], VertexColors -> Hue /@ data[[All, 4]]], Axes -> True, BoxRatios -> {1, 1, 1/GoldenRatio}]

plotting - Mathematica: 3D plot based on combined 2D graphs

I have several sigmoidal fits to 3 different datasets, with mean fit predictions plus the 95% confidence limits (not symmetrical around the mean) and the actual data. I would now like to show these different 2D plots projected in 3D as in but then using proper perspective. In the link here they give some solutions to combine the plots using isometric perspective, but I would like to use proper 3 point perspective. Any thoughts? Also any way to show the mean points per time point for each series plus or minus the standard error on the mean would be cool too, either using points+vertical bars, or using spheres plus tubes. Below are some test data and the fit function I am using. Note that I am working on a logit(proportion) scale and that the final vertical scale is Log10(percentage). (* some test data *) data = Table[Null, {i, 4}]; data[[1]] = {{1, -5.8}, {2, -5.4}, {3, -0.8}, {4, -0.2}, {5, 4.6}, {1, -6.4}, {2, -5.6}, {3, -0.7}, {4, 0.04}, {5, 1.0}, {1, -6.8}, {2, -4.7}, {3, -1.
