[R-sig-Geo] Error in writeRaster?

[Diann Prosser]

Hi all,

I'm running the latest version of R (info below) with the raster and rgdal
libraries loaded.
I get the following error when trying to write to a raster (one I have not
seen before with previous runs of this code):

> rRisk_mn <- writeRaster(risk_mn, 'risk_mn.tif', format=raster,
> overwrite=TRUE)  # for ArcGIS
*Error in function (classes, fdef, mtable)  : 
  unable to find an inherited method for function "writeRaster", for
signature "matrix", "character"*

More code is supplied below in case it's helpful. Thanks for any help in
fixing this error.

Kind regards,
Diann
