[R-sig-Geo] write .flt format in R

[Michael Sumner]

You could use rgdal instead:

library(raster)
library(rgdal)
x <- raster(volcano, crs = "+proj=laea")
## so rather than
## writeRaster(x, "file.flt")
writeGDAL(as(x, "SpatialGridDataFrame"), "file.flt", drivername = "EHdr")

## see this for the drivers available
gdalDrivers()

But that format is not very well defined, so I would test carefully
that your target is satisfied.

See here for some info:

Cheers, Mike.
