[R-sig-Geo] Help converting matlab raster to R raster brick

[cmundy]

Hi All,

I have been provided with a .mat file containing a time series of Sea
Surface Temperature data (50 x 42 cells with 92 time layers). It was a
"Struct" object in Matlab. I can happily import the file in to R using
R.matlab, creating a list as follows. My question is how then to convert
this to a raster brick?

Thanks

Craig
