[FORGED] Generating random data with non-linear correlation between two variables

Hi All, I am new to R and don't know how to achieve it. I am interested in generating a hypothetical dataframe that is consisted of say two variables named v1 and v2, based on the following constraints: 1. The range of v1 is 500-1500. 2. The mean of v1 is say 1100 3. The range of v2 is 300-950. 4. The mean of v2 is say 400 5. There exists a positive trend between these two variables, meaning that as v1 increases, v2 be also increase. 6. But the trend should be slightly non-linear. i.e., curved line. Is it possible to automatically generate through functions like rnorm. Any help will be highly appreciated.
This sounds to me very much like a homework problem. We don't do people's homework for them on this list. cheers, Rolf Turner
