Try extracting the unique coordinates as vectors, e.g. x <- sort(unique(lon)) y <- sort(unique(lat)) filled.contour(x, y, z100) The sensibility of that depends on the numeric uniqueness of your coordinates, if length(x) and length(y) are not now equal to** the corresponding dim(z100) then tha

I am using the RNetCDF package to extract data from netcdf files. I've got a nc file (from an atmospheric model) with coordinates as the following: >dim(lon) [1] 67 46 > dim(lat) [1] 67 46 I suppose the lon and lat values are given to grid points. If I get the variables and plot(lon,lat) it shows
