如何在R中的新向量中合并向量元素

Question

I want to extract the elements of each vector and get new vector that attached the elements

x<-c(1,2,3,4)
y<-c(w,w,w,w)
z<-c(1,2,3,4)

Expected result

xyz<-c(1w1,2w2,3w3,4w4)

Thank you

Answer 1

I think a pretty straightforward paste0 will get it done here.

> x <- 1:4; y <- rep("w", 4); z <- 1:4
> (xyz <- paste0(x, y, z))
# [1] "1w1" "2w2" "3w3" "4w4"

cat would also work,

> cat(paste0(x, y, z), sep = ",")
# 1w1,2w2,3w3,4w4

Answer 2

Also,

as.character(interaction(x,y,z,sep=""))
#[1] "1w1" "2w2" "3w3" "4w4"
