It is unclear a) which emails, since you have been having an offlist correspondence with Mendelssohn, and b) why Holtman's solution offered two weeks ago is not satisfactory.

As a reminder, it was, with very slight modifications:

colkey <- colorRampPalette(c('red','blue'))(32) levelplot(dat, colorkey=list(col=colkey),

col.regions=(col=colkey))

If the problem has changed then perhaps a new posting with a subject line that matches the question and content that is self-contained would be more effective.
