Hi, I have a problem with writeRaster when writing a brick to NetCDF - the names of the layers are not preserved. Here is a minimum example to demonstrate the point:
#Create an arbitrary brick and write it out b <- brick(system.file("external/rlogo.grd", package="raster")) fname <- file.path( tempdir(),"test.nc") dmp <- writeRaster(b,file=fname) #Now read it back in a <- brick(fname) #However, names are not preserved > names(b) [1] "red" "green" "blue" > names(a) [1] "X1" "X2" "X3" > I realise this is a touch tricky, as NetCDF isn't exactly made for storing character strings, which is how raster stores the layer names. However, there are many cases where the string is just a representation of a number anyway.... e.g. when working with time or depth levels as the layers in the brick. One solution could therefore be to allow the writeRaster function to take an argument "zvals", in the same way that it takes "zname" and "zunit" when working with netcdf files - this argument would let you specify the numeric values of the z-axis. Everything else would then work ok I think, as brick() picks up the values of the z-axis, converts them to strings and assigns them to layer names.
