如何在给定一组向量的情况下创建新数据集？

导读：在R中是否有办法建立一个由给定的一组向量组成的新数据集 – median1,median2,median3,median4–它们是来自先前数据集的中值向量？ median1 = apply(s[,c("A1","B1","C1","D1","E1","F1","G1","H1","I1")],1,median)median2 = apply(s[,c("A2","B2","C2","D2

在R中是否有办法建立一个由给定的一组向量组成的新数据集 – median1,median2,median3,median4–它们是来自先前数据集的中值向量？

median1 = apply(s[,c("A1","B1","C1","D1","E1","F1","G1","H1","I1")],1,median)
median2 = apply(s[,c("A2","B2","C2","D2","E2","F2","G2","H2","I2")],median)
median3 = apply(s[,c("A3","B3","C3","D3","E3","F3","G3","H3","I3")],median)
median4 = apply(s[,c("A4","B4","C4","D4","E4","F4","G4","H4","I4")],median)

plot(median1,pch = ".")

解决方法

你是什??么意思“建立一个新的数据集”？像这样？

s2 <- data.frame(median1,median4)

或者使用cbind：

s2 <- cbind(median1,median4)
