R转置日期框架并设置列标题

如何解决R转置日期框架并设置列标题

我有一个要转置的数据框（我想转置是正确的单词）。 下面的代码将给出简化的数据框。

tests <- c("TestA","TestB","TestC")
bg <- c(23,13,15)
s1 <- c(21,15,17)
s2 <- c(27,25,11)
s3 <- c(24,14,18)
df <- data.frame(tests,bg,s1,s2,s3)

我想对此进行转置/重塑以使其具有以下结构：

请记住，最多可能有20个测试和50个系列（s1，s2 .... s50）

解决方法

以长格式获取数据，并将变量更改为宽格式：

newlist = sorted(list_of_snaps,key=lambda k: k['snap_id'])

或者使用library(tidyr) df %>% pivot_longer(cols = -tests) %>% pivot_wider(names_from = tests,values_from = value) # name TestA TestB TestC # <chr> <dbl> <dbl> <dbl> #1 bg 23 13 15 #2 s1 21 15 17 #3 s2 27 25 11 #4 s3 24 14 18 data.table + dcast

标准data.table::transpose-程序

data.table::transpose( df,make.names = "tests",keep.names = "name" )

#   name TestA TestB TestC
# 1   bg    23    13    15
# 2   s1    21    15    17
# 3   s2    27    25    11
# 4   s3    24    14    18
