but I get distinct results for
the T-test (in summary(lm.object) function) and

shouldn't this two approach give me the same result, i.e
to indicate the same significants terms in both tests???????
obs.
The system has two restrictions:
1) sum( x_i ) = 1

Hessian in box-constraint problem - concern OPTIM function

I am using the OPTIM function with particular interest in the method
L-BFGS-B,
because it is a box-constraint method.
I have interest in the errors estimates too.
I make:

filled maps
Hi R-Help,
I would like to make filled contour maps of ocean data overlaid by
costlines from the map package.
I can draw the filled contours and the coastlines om the same plot, but
the filled contour also covers part of the land. To get rid of that I
tried to draw a filled coastline map on top of the filled contour, but
the filled map only draws the closed contours - so most of the land is
