mode

https://docs.python.org/3/library/gzip.html I am considering to use gzip.open() , and I am a little confused about the mode argument: The mode argument can be any of 'r', 'rb', 'a', 'ab', 'w', 'wb', 'x' or 'xb' for binary mode, or 'rt', 'at', 'wt', or 'xt' for text mode. The default is 'rb'. So what is the difference between 'w' and 'wb' ? The document states they are both binary mode . So does that mean that there is no difference between 'w' and 'wb' ? It means that r defaults to rb , and if you want text you have to specify it using rt . (as opposed to open behaviour where r means rt , not

I am still relatively new to R, so apologies in advance if my question seems too basic. My problem is as follows: I have a data set containing several factor variables, which have the same categories. I need to find the category, which occurs most frequently for each observation across the factor variables. In case of ties an arbitrary value can be chosen, although it would be great if I can have more control over it. My data set contains over a hundred factors. However, the structure is something like that: id <- 1:3 var1 <- c("red","yellow","green") var2 <- c("red","yellow","green") var3 <-

Is there another way in numpy to realize scipy.stats.mode function to get the most frequent values in ndarrays along axis?(without importing other modules) i.e. import numpy as np from scipy.stats import mode a = np.array([[[ 0, 1, 2, 3, 4], [ 5, 6, 7, 8, 9], [10, 11, 12, 13, 14], [15, 16, 17, 18, 19]], [[ 0, 1, 2, 3, 4], [ 5, 6, 7, 8, 9], [10, 11, 12, 13, 14], [15, 16, 17, 18, 19]], [[40, 40, 42, 43, 44], [45, 46, 47, 48, 49], [50, 51, 52, 53, 54], [55, 56, 57, 58, 59]]]) mode= mode(data, axis=0) mode = mode[0] print mode >>>[ 0, 1, 2, 3, 4], [ 5, 6, 7, 8, 9], [10, 11, 12, 13, 14], [15, 16,

What is the difference between Spark standalone and Local mode? Spark standalone is a resource manager which can work on a cluster. It is simply the built in resource manager as opposed to an external one like yarn. Spark local runs without any resource manager, everything runs in a single jvm (you can decide the number of threads). This is aimed for testing locally. 来源： https://stackoverflow.com/questions/40828302/difference-between-spark-standalone-and-local-mode

I'm looking for an elegant way of determining which element has the highest occurrence (mode) in a C++ ptr array. For example, in {"pear", "apple", "orange", "apple"} the "apple" element is the most frequent one. My previous attempts have failed EDIT: The array has already been sorted. int getMode(int *students,int size) { int mode; int count=0, maxCount=0, preVal; preVal=students[0]; //preVall holds current mode number being compared count=1; for(int i =0; i<size; i++) //Check each number in the array { if(students[i]==preVal) //checks if current mode is seen again { count++; //The amount of

I'm developing a project using Laravel 5 and AngularJS. I want to enable $locationProvider.html5Mode(true); and stop the page from reloading. The page doesn't reload when I set it to false and visit a link. Here is my route.php Route::get('/', function () { return View::make('index'); }); Angular code app.config(function($routeProvider, $locationProvider) { $routeProvider.when('/', { templateUrl: 'views/feed.html', controller: 'fdController' }).when('/collections', { templateUrl : 'views/collections.html', controller: 'clController' }).otherwise({ redirectTo : '/' }); $locationProvider

I have a question about running an app in the background. I know about how to do it, but Apple does not like the way I'm doing it. To get you on the same page, I have a security app, and I need to it monitor the device even when it is in the background. It is sort of like a burglar alarm. I was using background audio mode, thinking it would be okay because I will be playing a sound when it is triggered. Needless to say, Apple didn't like that. So I added a ping! It pings while active, therefor playing background audio while in the background. Once again, they didn't like that either. My app
