transpose()函数是R语言中一个非常方便的函数,可以直接将数据转置为dataframe。 下面是一个示例,展示了如何使用transpose()函数将数据转置为dataframe: # 创建一个示例数据框data<-data.frame(Name=c("Alice","Bob","Charlie"),Age=c(25,30,35),Gender=c("Female","Male","Male"))# 使用transpose()函数进...

本文来源于 2018 年学习《R for Data Science》写的笔记。一起复习一下吧~ 函数有3个好处: 更容易看清代码意图 更容易对需求变化做出反应(改变) 更容易减少程序bug 除了函数,减少重复代码的另一种工具是迭代,它的作用在于可以对多个输入执行同一种处理,比如对多个列或多个数据集进行同样的操作。
It handles atomic vectors, lists, data.frames and data.tables as input and returns the number of unique rows. Closes #884. Gains by argument. Closes #1080. Closes #1224. Thanks to @DavidArenburg, @kevinmistry and @jangorecki. Implemented transpose() to transpose a list and tstrsplit ...
