Better to use inherits().

Yes indeed, as Steve said, really do!
I don't use JRI, but the data seem to be there. If you are looking for the row

Does the package semPlot not do what you want? I notice that you got
an error when you used library(semPlot) because you don't have all the
dependencies installed. When you have semPlot working, it should be
able to produce a graphical output of the results, including
'covariance arrows'.

You may want to consider another way of getting your answer that takes

Not an answer to your question, but you should not be using dummy

Thanks a lot. This is the option I found later.

The easiest way is to find out what the actual projection is, and
reconstruct a sensible representation of the grid.
Usually you have to guess, but it's possible to figure out. You *can* plot
by building a proper mesh in longlat, but my preference is full rescue. You
need to know the projection

You probably need to set some graphics parameters such as xpd and mar (see
