When I go to that section, http://www.wolfram.com/language/fast-introduction-for-programmers/en/strings/, I don't see `StringReplace["lead",_"gold"]`, which isn't valid syntax. I see `StringReplace["lead",_ -> "gold"]`
It looks like you have some variables already defined as interpolating functions from a previous evaluation. Try restarting the kernel reevaluating.
I would recommend not using the letter `D` for a symbol in your equation. [`D`](http://reference.wolfram.com/language/ref/D.html) is a built in symbol, which is why it shows up as black in a notebook without you having defined it. It doesn't give...
Is having a fixed number of edges the only criterion, or do you also need them to be connected graphs? If you only want the subgraphs with a given number of edges, regardless of whether they are connected, you can use `Subsets` ...
This is the normal behavior with 2D plotting functions, the values are rescaled to lie between 0 and 1 *before* being fed to the color function. If you use the option `PlotLegends -> Automatic` you can see the color mapping that is being used. Use...
Just to clarify, this is the normal behavior ``` In[7]:= Length@Table[x, {x, 0, 1, .1}] Out[7]= 11 ``` When you do something drastic like ``` $PreRead = (# /. s_String /; StringMatchQ[s, NumberString] && ...
[@Murray Eisenberg][at0], try opening Mathematica from the command line to have access to your usual $PATH. For me, I enter in the terminal /Applications/Mathematica-11.2.app/Contents/MacOS/Mathematica & and in the front end that pops up,...
Following the inputs from the page you linked, data = ResourceData["Tornadoes in the U.S., 1950-2015"]; The data in question is now loaded into memory (and stored as a `LocalObject` so you don't have to redownload it). Now you can do what...
I don't believe there is a way to make the new store permanent, I think at startup the `$EntityStores` is empty by design. But you **can** add the relevant code to your .init file, where you can keep any code you want executed when the kernel...
Glad to help. The way I found it was by searching for symbols with "Font" in the name, In[5]:= Names["*Font*"] Out[5]= {"DefaultFont", "DefaultFontProperties", "Font", "FontColor", "FontFamily", "FontForm", "FontName",...
