change: Change field header

In rcdo: Wrapper of 'CDO' Operators

Change field header

Description

This module reads fields from infile, changes some header values and writes the results to outfile. The kind of changes depends on the chosen operator.

Arguments

ifile	String with the path to the input file.
code	INTEGER - Code number
oldcode	INTEGER - Pairs of old and new code numbers
newcode	INTEGER - Pairs of old and new code numbers
oldparam	STRING - Pairs of old and new parameter identifiers
newparam	STRING - Pairs of old and new parameter identifiers
name	STRING - Variable name
oldname	STRING - Pairs of old and new variable names
newname	STRING - Pairs of old and new variable names
oldlev	FLOAT - Old level
newlev	FLOAT - New level
ofile	String with the path to the output file.

Details

chcode    Change code number
          Changes some user given code numbers to new user given values.
chparam   Change parameter identifier
          Changes some user given parameter identifiers to new user given values.
chname    Change variable or coordinate name
          Changes some user given variable or coordinate names to new user given names.
chunit    Change variable unit
          Changes some user given variable units to new user given units.
chlevel   Change level
          Changes some user given levels to new user given values.
chlevelc  Change level of one code
          Changes one level of a user given code number.
chlevelv  Change level of one variable
          Changes one level of a user given variable name.

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.
