[GRASS-user] g.region in R

[Sam Prentice]

Hi, 

 

I study dirt and landforms and I have what (I think) is a very basic
question, unless you're a new GRASS user like me.

 

I've created DEM derivatives in GRASS (via qGIS) and I'm trying to parse
them within R using gmeta6(). I know little about GRASS file structure, but
it's evident that g.region is a metadata file of spatial parameters, and
that I need to point R towards it, but I can't find the file or get around
this error. This may be more of an R question than a GRASS one, but any
suggestions are welcome. Code and errors printed below.

 

Thanks,

Sam 

 

 

#load GRASS region data
gmeta6 <- gmeta6()



#read in our 7 raster files from GRASS
x <- readFLOAT6sp(c("er","crosc","longc","slope","profc","minic","maxic"))



> ?gmeta6

> gmeta6 = gmeta6()

Error in system(cmd0, intern = TRUE) : 'g.region.exe' not found

Error in parseGRASS(cmd) : g.region not found

> ?g.region

No documentation for 'g.region' in specified packages and libraries:

you could try '??g.region'

> ??g.region
