...the objective is to get a much smaller dataframe and the unique values for ID is 1409 with the minimum and maximum pressure for each profile. The slow part is: h.maxmin <- by(p.1,p.1$id,function(x){ data.frame(id=x$id[1], maxp=max(x$p), minp=min(x$p))}) 2. Even with unneeded data objects removed, this is very slow. Is there a faster way to get the maximum and minimum values? platform sparc-sun-solaris2.9 arch sparc os solaris2.9 system sparc, solaris2.9 status major...

...ulation unsatisfactory around that value. Not supplying the gradient avoids the error (by using a finite-difference model), but is unacceptably slow. Does anyone have an idea for a more clever way to preform what is effectively a simple quadratic programming problem on a discontinuous domain: {0, [minp, maxp]}?
