search for: methad

Hi, I have a function of the second grade, with 2 parameters: y~A^2 + A + B^2 + B The response y is a measurement for the precision of the analytical method, where A en B are method parameters. As its neccesary to keep the precision of the analytical methad as good as possible, its usefull to optimize A en B to keep y as low as possible. But how can I do this with R? I have searched the archives, did some search work in the help function ( optimize, nlm, nls, ...) but could find anything that looks like what I need. I have written a script which does...
