Dear all, I have installed necessary packages such as ncdf4 and RNetCDF. But still my machine can't read netcdf files into R. Below are the file formats and the respective errors:> open.nc("cru.ts3.23.1901.2014.tmx.dat.nc")Error: No such file or directory> open.nc("cru_ts3_23_1901_2014_pre_dat.nc")Error: NetCDF: Unknown file format I am using Windows 7 64-bit. Thanks for your suggestions and comments in advance Mamuash
