I have recently come across the code |> in R. It is a vertical line character (pipe) followed by a greater than symbol. Here is an example: mtcars |> head() What is the |> code doing?
What is difference in a string between \r\n, \r and \n? How is a string affected by each? I have to replace the occurrences of \r\n and \r with \n, but I cannot get how are they different in a stri...
I have seen the use of %>% (percent greater than percent) function in some packages like dplyr and rvest. What does it mean? Is it a way to write closure blocks in R?
二、R从哪里来? R是统计领域广泛使用的诞生于1980年左右的 S语言 的一个分支,可以认为R是S语言的一种实现。 而S语言是由AT&T贝尔实验室开发的一种用来进行数据探索、统计分析和作图的 解释型语言。 最初S语言的实现版本主要是 S PLUS。
今年年初开始接触R语言,自学兼修课,学了一个学期,暑期在某上市互联网公司找了一份纯粹用R语言工作的的数据分析实习,现在应该可以说熟练掌握R语言了。我的学习路径如下: 名师指导——学习coursera公开课; 巨人肩膀——浏览技术博客 几本入门书籍; 社区帮助——很多牛人只是比你更善用 ...
For Boolean values there’s no difference between bitwise and logical operations; but for arbitrary integers, the result differs. For instance, 1 | 2 == 3 in most programming languages. However, this is true for R: R coerces numeric arguments of & and | to logical values and performs Boolean arithmetic. … except when both arguments are of ...
The infix operator %>% is not part of base R, but is in fact defined by the package magrittr (CRAN) and is heavily used by dplyr (CRAN). It works like a pipe, hence the reference to Magritte's famous painting The Treachery of Images. What the function does is to pass the left hand side of the operator to the first argument of the right hand side of the operator. In the following example, the ...
R is a free, open source programming language and software environment for statistical computing, bioinformatics, information graphics, and general computing.
R是用于统计分析、绘图的语言和操作环境。R是属于GNU系统的一个自由、免费、源代码开放的软件,它是一个用于统计计算和 ...
综合来看,《GTA 6》延期的核心原因大概率在于R星对品质的极致追求、技术复杂性、团队管理挑战,以及商业策略的权衡。 尽管玩家可能对跳票感到失望,但结合R星多次跳票的历史表现来看,延期往往与最终质量正相关。
