如何在矢量的每个值之间写一个逗号？

Question

我想将矢量导出到每个值之间带逗号的文件.我试过用paste它sep = ","但它不起作用.有谁知道为什么？

> x <- rnorm(10)
> paste(x, sep = ",")
[1] "-1.08574649988891"  "2.9580381152357"    "-0.549880906960338" "1.79794352588269"   "-1.06316832291584"  "-1.56636513327118"  "0.363867572492577" 
[8] "-0.644707355221403" "0.617827074223129"  "-1.50892267338431" 

Answer 1

因为sep分离对象; collapse分离元素.

> paste(letters[1:3], 1:3, sep=",", collapse="|")
[1] "a,1|b,2|c,3"
