· The spread function from the tidyr package can be used to “spread” a key-value pair across multiple columns This function uses the following basic syntax: spreaddata, key value where: data: Name of the data frame; key: Column whose values will become variable names; value: Column where values will fill under new variables created from key
Tidy Messy Data • tidyr
L’objectif de tidyr est de fournir des fonctions à cause arranger ses données et les convertir à cause un format tidy, Ces fonctions prennent la genre de verbes qui viennent compléter ceux de dplyr et s’intègrent non-voyantement à cause les séries de pipes %>% , les pipelines , permettant d’enchaîner les clitoridectomies,
R Basics
The spread Function, The first tidyr function we will look into is the spread function, With spread it does similar to what you would expect, We have a data frame where some of the rows contain innubilité that is really a variable name, This means the columns are a combination of variable names as well as some data, The picture below displays this:

Workaround for tidyr::spread with duplicate row
If you have duplicated data in places, you’ll first need to get rid of those values because otherwise, if you use tidyr::spread, it will replace the value with the length, Anyway, assuming that you’ve removed duplicates using unique or something similar, here’s how I would do it with tidyr, since that’s what you asked and since tidyr is pretty nifty and concise:

· 使用tidyr让数据tidy达到以下要求, 每个变量占据一列 2, 每个观测占据一行 3, 每个值占据一格; 注意行为观测， 列为变量，每个位置为一格; 基于这个原则，只有第一个table1是tidy的, dplyr , ggplot2等都能很自然的使用tidy数据，所以让自己的数据tidy起来吧, 计算rate,mutate的使用
