Hi,
I would like to create an uniform random raster, similar to what i would
obtain in R with the following code

raster=raster(matrix(runif(54210, max=50, min=-50, 139,390) , ...........)
writeRaster(raster,filename=random.tif",formats=GTiff,overwrite=TRUE)

I read the explanation of
https://grass.osgeo.org/grass7/manuals/r.random.surface.html
and also r.mapcalc - random (a,b)
but I'm not sure if one of them produce the same concept/result.

Any input? or better explanation

Thanks
Best
Giuseppe
