What do you mean by removing them? Do you want the whole row/column
deleted? Have you tried setting them to NA so that the points are not
plotted? You have to be a little more specific on what type of action
you want to have happen when the criteria is met. Of course the
answer is "anything is possible in R".

> Hi, I apologise in advance for the naïve question. I have large matrices that I want to plot. I currently use color2D.matplot. However, these matrices contain many values of no interest (i.e. where there is no data, the figure -999 is automatically displayed). Is there any way of removing these from the matrices to be plotted by matplot? An obvious possibility is setting them all to 0, but that introduces 'false data'. I also see that matplot does not have a way of dealing with NaNs. Is this actually the case? Thanks in advance for any help you can give me!!
