"R": put all elements of a vector into one element without "paste"

Question

I have a vector for example test<-c("red","blue","green"). How can i join the elements of the vector into one so i have test<-c("red/blue/green").

I know I could use paste(test[1],test[2],test[3], sep="/") but that's too much work because my vector has hundreds of elements!

thx for your help!

Answer 1

You can use collapse parameter of paste

> paste(test , collapse ="/")
[1] "red/blue/green"
