Concatenate records of a variable across netCDF files

Concatenates the records of the same variable from multiple netCDF files along the unlimited dimension and writes the result to a new file.

Usage

nc_rcat(filenames, varid, output)

Arguments

filenames

Character vector with the paths to the input netCDF files.

varid

Character string giving the name of the variable to concatenate. If missing, the variable is inferred from the first file when possible.

output

Character string giving the path to the output netCDF file to create.

Value

Invisibly returns `output`.

Details

All files must contain the selected variable and must be compatible in all non-unlimited dimensions. The unlimited dimension is appended in the order given by `filenames`.
