distgrid: Distribute horizontal grid

In rcdo: Wrapper of 'CDO' Operators

Distribute horizontal grid

Description

This operator distributes a dataset into smaller pieces. Each output file contains a different region of the horizontal source grid. 2D Lon/Lat grids can be split into nx*ny pieces, where a target grid region contains a structured longitude/latitude box of the source grid. Data on an unstructured grid is split into nx pieces. The output files will be named <obase><xxx><suffix> where suffix is the filename extension derived from the file format. xxx will have five digits with the number of the target region.

Usage

cdo_distgrid(ifile, nx = NULL, ny = NULL, obase = NULL)

Arguments

ifile	String with the path to the input file.
nx	INTEGER - Number of regions in x direction, or number of pieces for unstructured grids
ny	INTEGER - Number of regions in y direction [default: 1]
obase	String with the basename of the output files.

Value

Operators that output one or more files return a character vector to the output files.

Operators that output an indefinite number of files return a string with the basename of the files.

Operatos that don't return filenames return a character vector with the string output.

Note

This operator needs to open all output files simultaneously. The maximum number of open files depends on the operating system!
