But the awesome thing is you don't need a for loop at all thanks to the magic of R's vectorization!
This will do it (and much faster than an R level loop would): x = 0:200 # Note that you don't need a c() since you aren't concatenating 0:200 with anything A <- dpois(x,exp(4.5355343)) B <- dpois(x,exp(4.5355343 + 0.0118638)) C <- dpois(x,exp(4.5355343 -0.0234615)) D <- dpois(x,exp(4.5355343 + 0.0316557)) E <- dpois(x,exp(4.5355343 + 0.0004716)) F <- dpois(x,exp(4.5355343 + 0.056437)) G <- dpois(x,exp(4.5355343 + 0.1225822)) Y = A + B + C + D+ E+ F + G plot(x, Y) I'd advise you to look around for a good R guide: (there are quite a few free online, many tailored to specific disciplines) vectorization is pretty sweet and if you don't get into it early, you'll find R to be much more cumbersome and slow than it truly is.
