R help - May 2010 - rworldmap

I am trying to get a legend to work in rworldmap.  I have no programing
experience and a newbie to R.

I will attach a very small database and R script that I am using - hope that
is OK.  I seem to get a legend using a vector in catMethod.  Howerver I get
error or warning messages regarding the colour palette and I'm sure that I
am not using the program  in the best way.

I would like the legend to make all five Maps comparable - so the colours
are the same for identical temperature trend ranges.  I would like the
ranges to be smaller - say 0.05 and have more colours (what are the
allowable colours?).  Maybe a description of cutvectors, catMethod and how
to enter their auguments would be informative.

Thanks

Steve H :]

I see that the script didn't make it.  So made script text file.
