Redefining n is probably not a good idea...

Oops! n is now a vector of length 2000.

[...snip...]

> y_obs <- y_model +c( rnorm(n*0.97, 0, 0.1), rnorm(n*0.03, 0, 0.5) )

now length(n*0.97) == 2000 > 1, so rnorm(n*0.97, ...) gets you a length 2000 vector (check ?rnorm), and  c() of 2 of those is a vector of length 4000.

[...etc...]
