[R-sig-Geo] writeRaster: BSQ despite BIL is requested

[Agustin Lobo]

Thanks Roger,

Just to summarize, not only the hdr files are correct, the hdr files
are consistent with the ordering in the data files:

require(rgdal)
require(raster)
m <- matrix(rep(10,20),ncol=5)
b <- brick(raster(m),raster(10*m),raster(100*m))
b
writeRaster(b, file="bwrast", format="ENVI", datatype="INT2U",
            bandorder="BIL", overwrite=TRUE)

writes a correct BSQ file, despite having requested BIL order

writeRaster(b, file="bwrast2", format="ENVI", datatype="INT2U",
            options="INTERLEAVE=BIL", overwrite=TRUE)

writes a correct BIL file (and this is a useful solution, thanks).

I tend to think that the fact that writeRaster() ignores
bandorder="BIL" is a bug.
