Hi,
I had the same issue in the past and I managed to solve it by:
a) removing rgdal
b) reinstalling gdal and libtiff libraries
c) reinstalling rgdal
Hope it helps.
Greetings,

Subject: [R-sig-Geo] problem with writeRaster and GeoTIFF format
Dear all,
I have a raster
class : RasterLayer
dimensions : 1639, 821, 1345619 (nrow, ncol, ncell)
resolution : 0.00887, 0.00833 (x, y)
extent : 43.21786, 50.50013, -25.60209, -11.94922 (xmin, xmax,
ymin, ymax)
coord. ref. : +proj=longlat +ellps=WGS84
data source : in memory
names : layer
values : 15.3815, 38.32809 (min, max)
I cannot write it to a GeoTIFF file:
> writeRaster(r, filename = "r.tif")
Error in .local(.Object, ...) : Unable to create dataset
The same thing happens after converting the raster to
SpatialGridDataFrame and using writeGDAL
> r.sgdf <- as(r, Class = "SpatialGridDataFrame")
> writeGDAL(dataset = r.sgdf, fname = "r.tif", drivername = "GTiff")
Error in .local(.Object, ...) : Unable to create dataset
I can write the raster to other formats (e.g. ESRI .hdr labelled). I can
also reproduce the .tif example in ?writeRaster.
Any hint?
Best wishes,
Renaud
