Yes, you can export sgrd to geoTIFFs via the "io_grid_gdal" module:
> library(RSAGA)
> rsaga.get.modules("io_grid_gdal")
$io_grid_gdal
code name interactive
1 0 Import Raster via GDAL FALSE
2 1 Export Raster via GDAL FALSE
3 2 Export Raster to GeoTIFF via GDAL FALSE
> rsaga.get.usage("io_grid_gdal", 2)
SAGA CMD 2.0.3
library path: C:/Progra~1/saga_vc/modules
library name: io_grid_gdal
module name : Export Raster to GeoTIFF via GDAL
Usage: 2 -GRIDS <str> [-FILE <str>]
-GRIDS:<str> Grid(s)
Grid list (input)
-FILE:<str> File
File path
But it seems that you can not control much about that geoTIFFs, hence I would
instead recommend
converting the sgrd files to ascii format, and then directly converting them to
geoTIFF using the
GDAL binaries (DOS prompt; http://www.gdal.org/gdal_translate.html) e.g.:
gdal_translate '-of' GTiff 'landsat1.asc' 'landsat1.tif'
Unfortunately, SAGA GRID format is not registered at GDAL (maybe you should
push this issue? try to
write to Olaf Conrad), so that you will always need to first convert to some
other GDAL-recognized
format before you can do any conversion.
Another alternative would be to read the SAGA grid format directly to R, e.g.
using the readBin
method (https://stat.ethz.ch/pipermail/r-sig-geo/2008-January/003079.html). But
I do not really know
the structure of the SAGA sgrd format, so I do not know how to set the
parameters.
Maybe Alex has more info?
cheers,

Subject: [R-sig-Geo] export .sgrd in tif with R+SAGA
Hi All,
Is It possible export a .sgrd grid in .tif image with R+SAGA?
Thanks
