IEEE Spectrum发布的2021年度编程语言排行榜,从涵盖社交网站、开源代码网站和求职网站的8个信息源:CareerBuilder、GitHub、Google、Hacker News、IEEE、Reddit、Stack Overflow和Twitter,按照11个指标收集数据,最终得到了数十种编程语言流行度的整体排名,如图0.6所示。 图0.6 IEEE
在R中的线条图中进行换行或空白可以通过调整标签的格式来实现。以下是一种常见的方法: 1. 使用`\n`进行换行:在标签中使用`\n`可以实现换行效果。例如,如果要在标签中进行换行,可以将标签文本分为...
Python did not quite "swallow" R, but the results, based on 954 voters, show that in 2017 Python ecosystemovertookR as the leading platform for Analytics, Data Science, Machine Learning. See also my follow-up post:Python vs R – Who Is Really Ahead in Data Science, Machine Learning? Whi...

在机器学习和数据挖掘领域,曾经的R包总是在单打独斗,如今也正在从整合技术方面迎头赶上Python,出现了tidy风格的tidymodels包,以及新一代的用于机器学习的mlr3verse包,这些包基于R6类面向对象、data.table神速数据底层和开创性的Graph-流模式(图/网络流有别于通常的线性流)。 写作本书的目的 我发现近几年出现的R...

R data frames regularly create somewhat of a furor on public forums like Stack Overflow and Reddit. Starting R users often experience problems with this particular data structure and it doesn’t always seem to be straightforward. But does it really need to be so?
Kaggler 绝大多数都是用 Python 和 R 这两门语言的。因为我主要使用 Python,所以本文提到的例子都会根据 Python 来。不过 R 的用户应该也能不费力地了解到工具背后的思想。 首先简单介绍一些关于 Kaggle 比赛的知识: 不同比赛有不同的任务,分类、回归、推荐、排序等。比赛开始后训练集和测试集就会开放下载。
You may obtain the word2vec word vectors trained with Trump supporters Reddit from here. This package provides a tiny version of the data small_reddit for reproducing the analysis. S2 <- c("mexicans", "asians", "whites", "blacks", "latinos") A2 <- c("respect") B2 <- c("disrespect...
这里(https://www.kaggle.com/benhamner/d/uciml/iris/python-data-visualizations)有一个在著名的 Iris 数据集上做了一系列可视化的例子,非常有启发性。 Statistical Tests 我们可以对数据进行一些统计上的测试来验证一些假设的显著性。虽然大部分情况下靠可视化就能得到比较明确的结论,但有一些定量结果总是更理想的...
