A basic tutorial of R 推荐一个R tutorial,刚好解决了我一个问题: 如果知道Z或者t统计量,如何通过R计算获得对应的P值 按照常规思路,一般都是知道两个向量,通过t.testT检验来计算P值,但其实也可以一些R函数从统计量获得P值 以下内容均来自上述Tutorial中的部分内容...
The data type of a single character to be stored in the string. The C++ Standard Library provides specializations of this class template, with the type definitions string for elements of type char, wstring, for wchar_t, u16string for char16_t, and u32string for char32_t. Traits Various ...
R for beginners: Some basic graphics code to produce informative graphs, part two, working with big data A tutorial by D. M. Wiig In part one of this tutorial I discussed the use of R code to produce 3d scatterplots. This is a useful way to produce visua
Now that we have had a brief yet important introduction to R, let’s go through some simple concepts of R programming : What are objects in R? R lets you save data by storing it inside an R object. What’s an object? Just a name that you can use to call up stored data. ...
In this lesson, we will explore some basic building blocks of the R programming language. In its simplest form, R can be used as an interactive calculator. Type 5 + 7 and press Enter. 5+7 [1] 12 R simply prints the result of 12 by default. However, R is a programming language and...
