mode

I have a large data set with 11 columns and 100000 rows (for example) in which i have values 1,2,3,4. Where 4 is a missing value. What i need is to compute the Mode. I am using following data and function ac<-matrix(c("4","4","4","4","4","4","4","3","3","4","4"), nrow=1, ncol=11) m<-as.matrix(apply(ac, 1, Mode)) if i use the above command then it will give me "4" as the Mode, which i do not need. I want that the Mode will omit 4 and display "3" as Mode, because 4 is a missing value. Thanks in advance. R has a powerful mechanism to work with missing values. You can represent a missing value

I would like to turn off the airplane mode if num>50, I implemented this code (from Toggle airplane mode in Android ) but when executed I get a force close, can any one help here? if(num>50){ // read the airplane mode setting boolean isEnabled = Settings.System.getInt( getContentResolver(), Settings.System.AIRPLANE_MODE_ON, 0) == 1; // toggle airplane mode Settings.System.putInt( getContentResolver(), Settings.System.AIRPLANE_MODE_ON, isEnabled ? 0 : 1); // Post an intent to reload Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED); intent.putExtra("state", !isEnabled);

For this problem, I am to write a method called mode that returns the most frequently occurring element of an array of integers. Assume that the array has at least one element and that every element in the array has a value between 0 and 100 inclusive. Break ties by choosing the lower value. For example, if the array passed contains the values {27, 15, 15, 11, 27}, your method should return 15. (Hint: You may wish to look at the Tally program from earlier in this chapter to get an idea of how to solve this problem.) I am having a problem seeing what is going wrong for a specific input. For

在看js代码时，有时会看到关于quirks mode(怪异模式)和strict mode(严格格式)的东西，一直也没深究怎么回事，只是零零碎碎的有些概念，最近终于受不了这种似懂非懂的感觉，决定好好学习总结一下。 1、quirks mode和strict mode是浏览器解析css的两种模式，或者可以称之为解析方法。目前正在使用的浏览器这两种模式都支持 。 2、历史原因。 当早期的浏览器Netscape 4和Explorer 4对css进行解析时，并未遵守W3C标准，这时的解析方式就被我们称之为quirks mode(怪异模式),但随着W3C的标准越来越重要，众多的浏览器开始依照W3C标准解析CSS，仿照W3C标准解析CSS的模式我们叫做strict mode(严格模式). 3、后来的浏览器虽然支持strict mode，但众多浏览器并未放弃支持quirks mode。 一个重要的原因就是为了之前大量在quirks mode下开发的网页能够得到正确的显示。所以，这些支持两种模式的浏览器当拿到一张网页时，所做的一个前期工作就是判断采取何种方式进行解析(判断条件后面会说)。注：Explorer 5仍然只支持quirks mode 4、浏览器如何判断何用哪种方式解析CSS？ 解决方案就是采用doctype声明，大多数浏览器采用下面的这些 判断规则 浏览器要使老旧的网页正常工作

I have an array of Strings: String[] stringArray = {"x", "y", "z", "x", "x", "y", "a"}; What is the quickest/most efficient way to order this into a smaller Collection in order of how frequent each String is with its frequency? I though about using the String as a key in a HashMap<String,Integer> but this wouldnt be sorted in terms of frequency My other method i considered is using a TreeMap<Integer, String[]> with a list of Strings with that integer, but there seems a lot of checking involved.. Im trying to avoid using more than one loop If possible as my String arrays will be much larger

How do you enable flyspell-mode to be automatically used for every file and every major mode as soon as Emacs is started? Also, is there an XML dictionary that does not mark XML tags as misspelled words? b4hand The answer from this question worked for me: How to enable automatic spell check by default? Furthermore, it appears to be more general, unlike the current voted answer. Add the following lines to your .emacs or init.el . (add-hook 'text-mode-hook 'flyspell-mode) (add-hook 'prog-mode-hook 'flyspell-prog-mode) Chances are, you don't really want flyspell-mode enabled for all modes, but
