Data in R are stored in vectors. A typical vector is a sequence of values all having the same storage mode (e.g., characters vectors, numeric vectors). See ?atomic for details on the atomic implicit classes and their corresponding storage modes: "logical", "integer", "numeri...

Currently there are numerous incompatibilities with .Net core. This will show status of NancyFx package status. This is grouped by functionality. Currently support is for Nancy 2.* which has not released a stable version yet. Nancy core Nancy : 2.0.0-clinteastwood Nancy Boostrappers Nancy.Bo...

package mypackage var PublicVar string = "Hello, dear reader!" //Calculates the factorial of given number recursively! func Factorial(x uint) uint { if x == 0 { return 1 } return x * Factorial(x-1) }

In SCSS variables begin with $ sign, and are set like CSS properties. $label-color: #eee; They are only available within nested selectors where they’re defined. #menu { $basic-color: #eee; color: $basic-color; } If they’re defined outside of any nested selectors, then they can be us...

Floating point literals provide values that can be used where you need a float or double instance. There are three kinds of floating point literal. Simple decimal forms Scaled decimal forms Hexadecimal forms (The JLS syntax rules combine the two decimal forms into a single form. We treat t...

function addTwo(a, b = 2) { return a + b; } addTwo(3) // Returns the result 5 With the addition of default function parameters you can now make arguments optional and have them default to a value of your choice.

function argumentLength(...args) { return args.length; } argumentLength(5) // returns 1 argumentLength(5, 3) //returns 2 argumentLength(5, 3, 6) //returns 3 By prefacing the last argument of your function with ... all arguments passed to the function are read as an array. In this examp...

function myFunction(x, y, z) { } var args = [0, 1, 2]; myFunction(...args); The spread syntax allows an expression to be expanded in places where multiple arguments (for function calls) or multiple elements (for array literals) or multiple variables are expected. Just like the rest parameters s...

Eclipse does not give you the possibility to change the font size of the views like 'Project Explorer' or 'Servers', which looks ugly on Linux since Eclipse uses the default (desktop) font size. But you can edit specific configuration files to get the proper font sizes. To fix this annoying font si...

There are some general Future trait implementations in the futures crate. One of them is implemented in futures::sync::oneshot module and is available through futures::oneshot function: extern crate futures; use std::thread; use futures::Future; fn expensive_computation() -> u32 { //...

You can pass parameters to the functions in tf.cond() using lambda and the code is as bellow. x = tf.placeholder(tf.float32) y = tf.placeholder(tf.float32) z = tf.placeholder(tf.float32) def fn1(a, b): return tf.mul(a, b) def fn2(a, b): return tf.add(a, b) pred = tf.placeholder(tf....

If you name your file lib_linux.go, all the content in that file will only be compiled in linux environments: package lib var OnlyCompiledInLinux string

Different platforms can have separate implementations of the same method. This example also illustrates how build tags and file suffixes can be used together. File main.go: package main import "fmt" func main() { fmt.Println("Hello World from Conditional Compilation Doc!&...
