tidyverse是一个 R 语言包套件，它包含了多个 R 包，这些 R 包都是用于进行数据清洗、分析和可视化的。
In our experience, novice R users had a hard time understanding thebroompackage function namestidy(),augment(), andglance(). To make them more user-friendly, themoderndivepackage wrappers have much more intuitively namedget_regression_table(),get_regression_points(), andget_regression_summaries(...
字符串处理在数据清洗中使用较多,tidyverse系列中的stringr包提供了一系列接口一致的、简单易用的字符串操作函数,足以代替R自带字符串函数。 3.1 字符串长度 library(stringr) str_length(c("a", "R for data science", NA)) ## [1] 1 18 NA str_pad(c("a", "ab", "abc"), 3) # 填充到长度为...
dplyr is such a helpful package that Rdocumentation.org shows that it is the single most popular R package (as of 3/23/2017.) As much of a blessing as these commands are, they’re also a curse to beginners as they’re more to learn. The main packages of dplyr, tibble, tidyr, ...

You can find more info in the tidyverse documentationpullWhen we work with data frames and we select a single column, sometimes we the output to be as.vector. We can achieve this with the pull() which is part of dplyr.Example: Let’s say that I want to run a t.test in the ...
the above way we suggest giving ourcdatapackage a try. We named the functionspivot_to_rowrecsandunpivot_to_blocks. The idea was: by emphasizing the record structure one might eventually internalize what the transforms are doing. On the way to that we have a lot of documentation and tutorials...
Pandas has the best performance but Tidyverse is exceptional in functionality and ease-of-use. Thus, data scientists can switch between programming language depending upon the necessities while performing analysis. This will enable them to optimise the code and reduce analysis processes. It is advisabl...

Yes means the package includes the functionality to complete this analysis. Yes + Docs means this step is explicitly shown in either the function documentation or a vignette. No† means that the package lacks explicit functionality, but generic R capabilities for statistical testing can be applied...
