如何在数据帧上使用pivot_longer（）来包含一组特定的列？
我有一个数据帧，如何在数据帧上使用pivot_longer（）来包含一组特定的列？,r,R,我有一个数据帧，df： df <- structure(list(estrogen = c(-2, 2, 0, 1, -3, 1, -1, 1), testosterone = c(-1.84, 1.14, -0.35, 0.68, -2.04, 1.08, -0.48, 0.58), growth_hormone = c(-1.81, 0.98, -0.42, 0.58, -0.73, 2.05, 0.66, 0.38), insulin = c(-1.58, 1.37, -0.1
dfdf <- structure(list(estrogen = c(-2, 2, 0, 1, -3, 1, -1, 1), testosterone = c(-1.84,
1.14, -0.35, 0.68, -2.04, 1.08, -0.48, 0.58), growth_hormone = c(-1.81,
0.98, -0.42, 0.58, -0.73, 2.05, 0.66, 0.38), insulin = c(-1.58,
1.37, -0.11, 0.89, -2.76, 0.39, -1.18, 0.17), treatment = c("2mg",
"2mg", "2mg", "2mg", "2mg", "2mg", "2mg", "2mg"), time = c("V3",
"V3", "V3", "V3", "V4", "V4", "V4", "V4"), type = c("lci", "uci",
"Estimate", "P", "lci", "uci", "Estimate", "P")), row.names = c(NA,
8L), class = "data.frame")
> df

8 1 0.58 0.38 0.17 2mg V4 P
如果ID列的名称没有任何定义功能（例如，因此我不能使用“contains”或类似的名称？我建议下一种方法。您可以在
pivot\u longer（）colslibrary(tidyverse)
#Data
df %>% pivot_longer(cols = -c(treatment,time,type)) %>%
select(name,value,treatment,time,type) %>% arrange(name)
name value treatment time type
1 estrogen -2.00 2mg V3 lci

另一种方法是使用

library(dplyr)
