You'll need to use the options= argument to pass through these values when
you instantiate the transient dataset. There is an example of its use in
?writeOGR.
Sorry, ?writeGDAL, of course. The valid options are given on the GDAL
supported formats pages for creation and/or copying - not (naturally) the
reading options.

The subsection of my code that I assume this belongs in is below:
driver="ENVI"
d.drv <- new("GDALDriver", driver)
tds.out <- new("GDALTransientDataset", driver = d.drv, rows =
dims[2],cols = dims[1], bands = bands, type = type)
gt <- c(offset[1] - 0.5 * cellsize[1], cellsize[1], 0.0,offset[2] +
(dims[2] -0.5) * cellsize[2], 0.0, -cellsize[2])
.Call("RGDAL_SetGeoTransform", tds.out, gt, PACKAGE = "rgdal")
.Call("RGDAL_SetProject", tds.out, file_projection, PACKAGE = "rgdal")
fn <- tempfile()
saveDataset(tds.out, fn)
Thanks!
