第一个是我觉得很好的函数,是两组的数据合并的函数,一开始自己只会在excel上运用相关的公式,但是发现这个包的运行比excel更快,是dplyer下面的full_join. 今天说的是图和把excel里面的宽表变成长表的函数pivot_longer函数,是tidyr包下面的一个函数。 函数的网页讲解:https://tidyr.tidyverse.org/reference/pivot_...
pivot_longer是 R 语言中tidyr包提供的一个函数,用于将宽格式的数据转换为长格式。这种转换在数据分析中非常常见,尤其是在需要对数据进行透视以便进行可视化或统计分析时。 基础概念 宽格式数据:每个观察值占据一行,多个变量可能分布在多个列中。 长格式数据:每个观察值占据一行,每个变量占据一列。

When you convert cells to formulas, these formulas access the same data as the PivotTable and can be refreshed to see up-to-date results. However, with the possible exception of report filters, you no longer have access to the interactive features of a PivotTable,...
