sethalo: Set the bounds of a field

In rcdo: Wrapper of 'CDO' Operators

Set the bounds of a field

Description

This operator sets the boundary in the east, west, south and north of the rectangular understood fields. Positive values of the parameters increase the boundary in the selected direction. Negative values decrease the field at the selected boundary. The new rows and columns are filled with the missing value. With the optional parameter value a different fill value can be used. Global cyclic fields are filled cyclically at the east and west borders, if the fill value is not set by the user. All input fields need to have the same horizontal grid.

Usage

cdo_sethalo(
  ifile,
  east = NULL,
  west = NULL,
  south = NULL,
  north = NULL,
  value = NULL,
  ofile = NULL
)

Arguments

ifile	String with the path to the input file.
east	INTEGER - East halo
west	INTEGER - West halo
south	INTEGER - South halo
north	INTEGER - North halo
value	FLOAT - Fill value (default is the missing value)
ofile	String with the path to the output file.

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.
