I'm new to R, so could someone please clarify the difference between paste() and paste0()? From what I've read on the internet, it appears like paste() and paste0() are the same thing.

=== paste("a", "b", sep="") paste0("a", "b") === paste("a", "b", sep="")

I, too, attempted something similar.

paste(a,b,sep = "_") paste(a,b,sep = "_") paste(a,b,sep = "_") paste(a,b,sep = "_") paste(a,b,sep = "_") paste(a,b,sep = "_") paste(a,b,sep = "_") paste(a,b,sep =

Using paste0, output "a y" "b w" "c q" ()

paste0(a,b,sep = "_") paste0(a,b,sep = "_") paste0(a,b,sep = "_") paste0(a,b,sep = "_") paste0(a,b,sep = "_") paste0(a,b,sep = "_") paste0(a,b,sep = "_") paste0(a,

**output**

"ay_" "bw_" "cq_" "ay_" "bw_" "cq_" "ay_" "b

Is it just that paste() uses a separator between elements and paste0() uses one after?
