fldmean(x)

Value

data.table

If `x` is a data.table, its columns should be named: "lon", "lat", "date", and "value"

If `x` is a filename, it should point to a *.nc file.

Examples

if (FALSE) {
download_data("gldas-vic", tempdir(), timestep = "yearly")
r <- raster::brick(paste0(tempdir(),
"/gldas-vic_tp_mm_land_194801_201412_025_yearly.nc"))
s <- fldmean(r)
