Somebody has already replied in probably more constructive terms. However, I would like to add a comment.
> Now, I would like to find the marginal distribution of y from the > bivariate distribution. The distribution of y is a theoretical property that cannot be _found_ from a data set. You can use a set of data to _estimate_ a distribution (this is what density() does), but if you want to _find_ the distribution of y then you have to take paper and pencil and work it out. R can do it for you numerically (using integrate()) but, again, in this case you don't need any data.
