Dear All,

I am new to the R-sig-Geo mailing list and new to R.

I write regarding any R function with which to plot level.colours onto a
spatial object.

I have a set of longitude and latitude coordinates with corresponding
explanatory variable for each coordinate location e.g. some measurement
such as tree height associated with each coordinate.

I write to ask whether it is possible in R to plot this measurements onto a
map (e.g. shape file or raster) or any map using levelplots and level
colors to show the distribution of the heights of these plants in raster
format in relation to the geographical location of these plants.

I attach a simple Excel file of an example of how my data would look like.

I will be glad if you could suggest a better way for me to arrange the data.

Thanks very much in anticipation of your response.

Barnabas
