[R-sig-Geo] Converting raster to a matrix

[John Wasige]

​Dear all,
Greetings!

I want to convert a big raster (see attached) a matrix, however, I get the
error below from the script. Anybody with an Idea on what is going wrong in
my script?

###Errors at the following point in the script​

> mat <- as.matrix(rast)Error in .local(x, ...) : 'x' has no values

#####script



​library(raster)
library(rgdal)

setwd('D:/Mobile_testdata')
image <- raster('D:/Mobile_testdata/SOSug_mean2qgis.tif')

rast <-  raster(image)
mat <- as.matrix(rast)

Thanks for your help

Rgds John
