[R-sig-Geo] writeGDAL: pseudocolor image?

[Agustin Lobo]

Thanks Vikram,

But that would be a multiband image, not a pseucolor image. I need
a single layer image including its colortable in the same file (i.e. a
temperature field
represented in color such as
https://sites.google.com/site/filestemp2/home/pseudocolorv2.tif  ).
Regards,

Agus
