Hello,
If you do this after the for loop, you'll get what you want:
paste(tre,collapse="")
(you can use whatever separator you want in the collapse argument)
But you don't even need the for loop, just do this instead of the for loop:
paste("con(",p," == ",c,", ",zest,", ",sep="",collapse="")
Best,
Miguel
