Perhaps I am missing something, but is there a Wolfram Community specific search field where I can look for particular posts? There is the overall WRI search in the upper right hand corner of the window, but as far as I can see, nothing to search...
I stumbled across this bug when I was playing with this (I have reported it) Execute ResourceData["Animal Weights Sample Data"] Now ask for information about the Dataset function: ? Dataset the following is returned: ...
Say one has a function, f, and a list, {a,b,c,d}. And say that that it makes sense to construct f[a][b][c][d] Which is the same as (((f[a])[b])[c])[d] I want to be able to do this with a single function that takes 2...
Your syntax is not quit right. Define the function like this: f[x_] := 3 x - 2 then f yields 13 Take a look at the references in this link so you can start to learn Mathematica ...
Recently (or perhaps longer) the time it takes to initially load the Wolfram Community page at its base URL has become very slow. I time it as around 25 seconds on each of the three browsers on my OSX system from when I first enter the link to when...
Since there are many folks on this forum that are new to using Mathematica/WolframLanguage I'd suggest that each order a copy of Stephen Wolfram's soon-to-be-released (December 7 2015) "An Elementary Introduction to the Wolfram Language": ...
Can a monkey type Shakespeare's works by only using words randomly appearing from the digits of Pi? I think it's a challenge... But perhaps we can use Pi to define a restricted subset of the English Language.... Here is a function...
Here is a set of dates: events = {{2014, 12, 14, 15, 26, 20.}, {2014, 12, 14, 15, 38, 31.}, {2014, 12, 14, 15, 41, 14.}, {2014, 12, 19, 11, 55, 11.}, {2014, 12, 19, 11, 55, 47.`}} Now I would like to find clusters of dates by using a...
Is there a way to test whether (for desktop Mathematica) in the middle of a calculation whether there is internet connectivity? The reason is that, if there is no internet connectivity (e.g., WIFI is turned off for the computer) then for my...
Difference in behavior between RegionNearest for a polygon's centroid in 2D vs 3D Consider a simple 2-d polygon whose centroid is outside of the polygon: Here is the polygon: region = Polygon[{{0, 0}, {1, 1}, {2, 0}, {1, 3/4}}]; ...
