This is a textbook for a quick start on data analysis in R. […] R下载链接：点击任意站点，进入后，选择下载与操作系统匹配的R软件。 RStudio下载链接 练习题链接 R之所以广受欢迎，很大一个原因就是它拥有种类繁多的“包”以满足我们的多种需求。尽管R自带一些功能强大的“包”，但是我们在需要的时候还得额外安装“包”，否则，调用包就会报错。 这时就需要用到install.packages()函数。例如，当我们需要安装tidyverse包时，可以输入install.packages(“tidyverse”)。 我们如果需要使用某一个“包”，则需要在开始时使用library()函数调用它。例如，我们在安装完tidyverse包后，调用它时可以输入 library(tidyverse)。 … Read more →

In many countries and regions, migration is becoming or already is the largest component of population change and important mechansim for both social and economic change. However, migration data is often of poor quality, missing or provided without disaggregation. Methods to estimate migration flows have been developed by demographers and other researchers to help address shortfalls and provide a platform to better understand patterns, trends and consequences. This manaul explores methods for measuring, estimating and visualising migration flow data, and their implementation in R. Readers will become familiar with useful R functions for handling migration data, a range of measures to summarise and compare migration systems, common estimation methods to overcome inadequate or missing migration data and recently developed methods to visualize complex migration patterns. While plenty of code samples and exercises are provided throughout the manual to build up the readers experience, some prior knowledge is required on how to handle and plot data using the tidyverse set of R packages.

A guide to the tidyverse for POL345 Students. […] POL345 is often Princeton students’ first foray into the programming language R. Through POL345, students gain an introductory overview of R, and programming generally, to conduct basic data analysis on their own. However, many further courses (SML201, SOC306, POL346), along with industry users of R, use the tidyverse instead, a “language” within R to conduct clean, readable data analysis. This book seeks to bridge that gap, revisiting each of the POL345 handouts using the tidyverse to introduce students to this “language within a language”. … Read more →

Working through ISLR with the tidyverse and tidymodels […] I am a data scientist and statistician who is (mostly) self-taught from textbooks and generous people sharing their work online. Inspired by projects like Solomon Kurz’s recoding of Statistical Rethinking and Emil Hvitfeldt’s ISLR tidymodels labs, I decided to publicly document my notes and code as I work through An Introduction to Statistical Learning, 2nd edition by Gareth James, Daniela Witten, Trevor Hastie, and Robert Tibshirani. I prefer to work with the tidyverse collection of R packages, and so will be using those to wrangle … Read more →

Simple cookbook for functions and idioms within the scope of the tidyverse. […] The basic idea of this book is to provide a documentation of the tidyverse written in a solution driven cookbook style. As an extra I would like to provide similar solutions based on base R functionality. Some reasons to write this book: One strength of the tidyverse is that it hides a lot of quirks that base R provides and inherits to many packages that rely on it. This allows to stick to a specific workflow from the point you enter the tidyverse until you leave it. This is why I highly recommend to head your … Read more →
