Clash Royale CLAN TAG #URR8PPP Moving average with changing window I would like to calculate the moving average of a variable in R with a changing window size. To be more specific: The moving average should be calculated over three years, but the data (time-series) is available in higher frequency and the window size can vary for each three-year window. Assume the following dataset: library(data.table) set.seed(1) # reproduceable data dataset <- data.table(ID=c(rep("A",2208),rep("B",2208)), x = c(rnorm(2208*2)), time=c(seq(as.Date("1988/03/15"), as.Date("2000/04/16"), "day"),seq(as.Date("1988/03/15"), as.Date("2000/04/16"), "day"))) The three-year moving average of the variable x should be calculated for both of the IDs (person A and B). Can this be done with zoo and datatable preferably? But any solution is fine. zoo datatable Please note I know how to do this with a fixed window size, the proble...

Clash Royale CLAN TAG #URR8PPP Codewars Challenge - Count of positives / sum of negatives My code works but it's not being accepted in order to pass the challenge. Any help on what I'm doing wrong would be appreciated. Challenge Description: Given an array of integers. Return an array, where the first element is the count of positives numbers and the second element is sum of negative numbers. If the input array is empty or null, return an empty array: C#/Java: new int / new int[0]; C++: std::vector<int>(); JavaScript/CoffeeScript/PHP/Haskell: ; Rust: Vec::<i32>::new(); ATTENTION!

Clash Royale CLAN TAG #URR8PPP Is there a method to generate a UUID with go language I have code that looks like this: u := make(byte, 16) _, err := rand.Read(u) if err != nil return u[8] = (u[8] | 0x80) & 0xBF // what does this do? u[6] = (u[6] | 0x40) & 0x4F // what does this do? return hex.EncodeToString(u) It returns a string with a length of 32, but I don't think it is a valid UUID. If it is a real UUID, why is it a UUID, and what is the purpose of the code that modifies the value of u[8] and u[6] . u[8] u[6] Is there a better way of generating UUIDs? 12 Answers 12 u[8] = (u[8] | 0x80) & 0xBF // what's the purpose ? u[6] = (u[6] | 0x40) & 0x4F // what's the purpose ? These lines clamp the values of byte 6 and 8 to a specific range. rand.Read returns random bytes in the range 0-255 , which are not all valid values for a UUID. As far as I can tell, this should be done for all the values in the slice though. rand.Read 0-255 If you are on linux...

Clash Royale CLAN TAG #URR8PPP Adds new method to Array.prototype in javascript [duplicate] This question already has an answer here: I am new to Javascript language, recently I started looking into js prototype and got confused by some odd output in below code: Array.prototype.print = function() console.log(this) [1, 2, 3, 4].print(); Could anyone tell me why it returns Cannot read property 'print' of undefined' If I declare var array = [1, 2, 3, 4] then call print function by array.print() , it works fine, so I got confused how is that different? var array = [1, 2, 3, 4] array.print() Array.prototype.print = function() console.log(this) var array = [1, 2, 3, 4] array.print() This question has been asked before and already has an answer.

Clash Royale CLAN TAG #URR8PPP Set equal height of specific elements using CSS only? I have 2 columns of data, in each column I have a paragraph and an image. I am wondering if there is a CSS-only method of making the paragraphs have the same height so that the images line up. I know I could loop through with JavaScript to find the tallest paragraph and set the height of the other to that, but I'm hoping to find a CSS solution if possible. Additionally, I cannot modify the DOM structure. .container display:flex; .col padding:0 15px; <div class="container"> <div class="col"> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Clash Royale CLAN TAG #URR8PPP function returning data but not showing I have this component const SummaryBar = props => const MainObject = props; const localGetUserFromID = userID => getEmailFromId(userID).then(results => return results.data.Title; //Comment: This one returning friendly name ); ; return (<span>Hello localGetUserFromID(MainObject.AuthorId)</span>) but when I render it somehow the its only showing Hello and not the output I am getting from my localGetUserFromID function. Am I doing wrong? Note the AuthorId is being pass to an API and the MainObject came from the App Level, FYI when I try to debug it using dev tools the function is retuning the text I am look for. You have an async function, meaning the data isn't available as return value of your promise call, but only available when it has completed. You should rather go for a stateful component, get the data in componentwillmount, and update the local state, and render that sta...
