installation - How can I install packages distributed as .paclet files?


I downloaded a Mathematica package. It came as a file with the .paclet extension. How can I install or uninstall it?




Answer



This answer is for people who are not interested in package development, and just need to install a Mathematica package which they obtained as a .paclet file.


Note: Before using the functions in this guide, it may be necessary to evaluate Needs["PacletManager`"]. Specifically, this is needed when your notebooks's default context is set to "Unique to This Notebook".


Installing


Packages distributed as paclets can be installed using the PacletInstall function. Evaluate this function with its argument the full path to the downloaded .paclet file.


For example, if SomePackage-1.0.0.paclet was downloaded into the ~/Downloads directory, then evaluate


PacletInstall["~/Downloads/SomePackage-1.0.0.paclet"]

You may use Insert → File Path... to easily insert the path to this file.


Getting information



.paclet files are typically named as SomePackage-1.0.0.paclet. Here SomePackage is the paclet name and 1.0.0 is its version. To get information about the active version of a currently installed paclet, use PacletInformation with its name:


PacletInformation["SomePackage"]

To list all installed versions of a paclet, use


PacletFind["SomePackage"]

Typically the latest version will be the active one. This is listed first by PacletFind.


Uninstalling


To uninstall all versions of a paclet named SomePackage, use


PacletUninstall["SomePackage"]


Warning: Mathematica uses many system paclets. Do not attempt to uninstall these. Only uninstall paclets that you have installed yourself.


Paclets with documentation


Packages that come with documentation may show up in the Documentation Center's Add-ons browser. Open the Documentation through the Help menu and look for the Add-ons and Packages link in the lower right corner:



Clicking it will show a list of those installed packages (both paclets and traditional ones) that come with documentation. The list may have buttons for opening the package's documentation or for uninstalling it.


Information for developers


If you are looking to distribute your own packages as paclets, read the following threads:

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[ ...

equation solving - Invert and fit implicitly defined curve

I need to fit an implicitly defined curve. I thought I could get some data out of Solve , and then using FindFit . Therefore, I would like to find the relation the parametric curve defined by $F(x,y)=0$: Solve[-(1/2) + 1/2 (0.41202 BesselK[0, 0.1 Sqrt[x^2 + y^2]] + (0.101483 x BesselK[1, 0.1 Sqrt[x^2 + y^2]])/Sqrt[x^2 + y^2]) == 0, y] But I can't get an output: Solve was unable to solve the system with inexact coefficients or the system obtained by direct rationalization of inexact numbers present in the system. Since many of the methods used by Solve require exact input, providing Solve with an exact version of the system may help. >> Edit: In particular, I would like to fit the data coming from the curve with the expression of another curve, and not with a function $f(x)$. In particular, since this clearly looks like a cardioid , I would like it to fit to something like it. What other strategies could I try?

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...
