Hi R users,
I have a maybe strange problem.
Normaly I do image.plot() with x,y coordinates and add=T and if I have some
NA values in my data matrix z, the color will be transparent of these
But now I have a disorted coordinate system and x,y are a matrix. It works
also fine, but now NA values are white colored and not transparent anymore.
It is problematic if I have a secondary information underlying.
Is there any solution for this stuff?
