[R-sig-Geo] Problem in reading .grd file using raster package

[Soumen Dey]

Hi all,

I have a .grd file on rainfall data (sharing the file link below). It
is a Geosoft
grid format file. The following error I encountered when I tried to read
that using 'raster' package.


> require(raster)
Loading required package: raster
Loading required package: sp

> x<-raster("rf_1984.grd") Error in .local(.Object, ...) : `C:\Users\Soumen
Dey\Desktop\rf_1984.grd' not recognised as a supported file format. Error
in .rasterObjectFromFile(x, band = band, objecttype = "RasterLayer", :
Cannot create a RasterLayer object from this file.


Can anybody can give any suggestions regarding this and help me reading
this file ?
