如何在R中制作成对向量列表? [英] How to make a list of pairwise vectors in R?

问题描述

我想对两类数据进行成对比较:假码(控件)和测量值，

I have two types of data that I want to do a pairwise comparison on: the shams (controls) and the measurements,

sham1 <- c('Sham1.r1', 'Sham1.r2', 'Sham1.r3')
sham2 <- c('Sham2.r1', 'Sham2.r2', 'Sham2.r3')
shams <- list(sham1, sham2)
day14 <- c('T14d.r1', 'T14d.r2', 'T14d.r3')
day90 <- c('T90d.r1', 'T90d.r2', 'T90d.r3')
measurements <- list(hour4, day1, day3, day7, day14, day90)

我想获得以下信息:

(('Sham1.r1', 'Sham1.r2', 'Sham1.r3'), ('T14d.r1', 'T14d.r2', 'T14d.r3')), (('Sham1.r1', 'Sham1.r2', 'Sham1.r3'), ('T90d.r1', 'T90d.r2', 'T90d.r3')), (('Sham2.r1', 'Sham2.r2', 'Sham2.r3'), ('T14d.r1', 'T14d.r2', 'T14d.r3')),  (('Sham2.r1', 'Sham2.r2', 'Sham2.r3'), ('T90d.r1', 'T90d.r2', 'T90d.r3'))

我想要的是:

The dput of what I want is:

list(list(c("Sham1.r1", "Sham1.r2", "Sham1.r3"), c("T14d.r1", 
"T14d.r2", "T14d.r3")), list(c("Sham1.r1", "Sham1.r2", "Sham1.r3"
), c("T90d.r1", "T90d.r2", "T90d.r3")), list(c("Sham2.r1", "Sham2.r2", 
"Sham2.r3"), c("T14d.r1", "T14d.r2", "T14d.r3")), list(c("Sham2.r1", 
"Sham2.r2", "Sham2.r3"), c("T90d.r1", "T90d.r2", "T90d.r3")))

推荐答案

apply(expand.grid(shams, measurements), 1, unname)
