Let's use *norm as an example. From the documentation: dnorm(x, mean = 0, sd = 1, log = FALSE) pnorm(q, mean = 0, sd = 1, lower.tail = TRUE, log.p = FALSE) qnorm(p, mean = 0, sd = 1, lower.tail = TRUE, log.p = FALSE) rnorm(n, mean = 0, sd = 1) So if I wanted to know the value of a standard no...

In order to define a variable inside a linq expression, you can use the let keyword. This is usually done in order to store the results of intermediate sub-queries, for example: int[] numbers = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }; var aboveAverages = from number in numbers l...

# load the library library(ggplot2) # create a blank canvas g <- ggplot(data = diamonds) g + geom_bar(aes(x = cut, fill = cut)) + scale_fill_discrete(guide = guide_legend(title = "CUT", keywidth = 2, ...

In order to enable a multidex configuration you need: to change your Gradle build configuration to use a MultiDexApplication or enable the MultiDex in your Application class Gradle configuration In app/build.gradle add these parts: android { compileSdkVersion 24 buildToolsVersion ...

The dexcount plugin counts methods and class resource count after a successful build. Add the plugin in the app/build.gradle: apply plugin: 'com.android.application' buildscript { repositories { mavenCentral() // or jcenter() } dependencies { classpath 'com.ge...

While in insert mode, press <C-o> to temporarily leave insert mode and execute a one-off normal command. Example <C-o>2w jumps to the second word to the left and returns to insert mode. Note: Repeating with . will only repeat the actions from returning to insert mode This allows for ...

C++11 introduced final specifier which forbids method overriding if appeared in method signature: class Base { public: virtual void foo() { std::cout << "Base::Foo\n"; } }; class Derived1 : public Base { public: // Overriding Base::foo void foo() f...

The URLRequest and URLLoader classes work together to make requests from Flash to external resources. The URLRequest defines information about the request e.g. the request body and the request method type, and the URLLoader references this to perform the actual request and provide a means of being n...

The URLVariables class allows you to define data to be sent along with a URLRequest. Example: var variables:URLVariables = new URLVariables(); variables.prop = "hello"; variables.anotherProp = 10; var request:URLRequest = new URLRequest('http://someservice.com'); request.data = v...

The URLRequestMethod class contains constants for the various request types you can make. These constants are to be allocated to URLRequest's method property: var request:URLRequest = new URLRequest('http://someservice.com'); request.method = URLRequestMethod.POST; Note that only GET and POST...

When Flash makes a request for data from an external source, that operation is asynchronous. The most basic explanation of what this means is that the data loads "in the background" and triggers the event handler you allocate to Event.COMPLETE when it is received. This can happen at any po...

Flash will not load data from a domain other than the one your application is running on unless that domain has an XML crossdomain policy either in the root of the domain (e.g. http://somedomain.com/crossdomain.xml) or somewhere that you can target with Security.loadPolicyFile(). The crossdomain.xml...

First define the circle radius and its center: var radius:Number = 100; var center:Point = new Point(35, 70); Then generate a random angle in radians from the center: var angle:Number = Math.random() * Math.PI * 2; Then generate an effective radius of the returned point, so it'll be inside ...

If you need to roll for a true or false in an "x% chance" situation, use: function roll(chance:Number):Boolean { return Math.random() >= chance; } Used like: var success:Boolean = roll(0.5); // True 50% of the time. var again:Boolean = roll(0.25); // True 25% of the time. ...

To get any random color: function randomColor():uint { return Math.random() * 0xFFFFFF; } If you need more control over the red, green and blue channels: var r:uint = Math.random() * 0xFF; var g:uint = Math.random() * 0xFF; var b:uint = Math.random() * 0xFF; var color:uint = r <&...
