tidyverse书籍的天花板

这是我见过关于tidyverse书籍中最好的, 可以说是天花板了(忍不住评论)!
百度找到的关于R语言编程的, 基本上都"沿用那些过时的、晦涩的R 语法".
tidyverse非常整洁、优雅, 但是相关书籍太少, 目前看过的就《R数据科学》,但是没有本书讲的详细,而且作者你还加入了自己“独到的理解体会”

谢谢作者, 期待后续章节的更新!!!

能否购买下纸质最新版本

张老师好,

读了下公开的这本书的部分,觉得很受益,之前学R的零碎的一些技巧自己也有感悟,很好的一本书。请问出版日期还要往后吗,可否付费购买纸质打印版本自己学习呢。

十分感谢!

good

一直在关注,可我看着不更新了呀,其实R包更新快速,在网络上发布更新才是理想的方式。

课件的Rmd

张老师您好,看您的课件像是Rmd转出来的,能否共享上相关的Rmd文件。感谢!

书内184页内的代码可能有误

同时修改列名的方法:

my_summarise = function(data, mean_var, sd_var) { data %>% summarise("mean_{{mean_var}}" := mean({{mean_var}}), "sd_{{sd_var}}" := mean({{sd_var}})) }

应该是

my_summarise = function(data, mean_var, sd_var) { data %>% summarise("mean_{{mean_var}}" := mean({{mean_var}}), "sd_{{sd_var}}" := sd({{sd_var}})) }

第二列应该想求的是SD

“将 case 列拆分为两列, 并删除原列”与“tstrsplit(DT$rate, split = "/")][, rate := NULL]”中的字符,似乎没有统一符号

感谢张老师对R语言资料的分享。张老师的R语言书籍,总结了常用的知识点和技巧,真的是良心之作。

ps: 书本2.7节(第200页),预计是笔误了(“将 case 列拆分为两列, 并删除原列”与“tstrsplit(DT$rate, split = "/")][,
rate := NULL]”中的字符,似乎没有统一符号)。

DT = as.data.table(table3)

将 case 列拆分为两列, 并删除原列

DT[, c("cases", "population") := tstrsplit(DT$rate, split = "/")][, rate := NULL]
