ymonarith: Multiyear monthly arithmetic

In rcdo: Wrapper of 'CDO' Operators

Multiyear monthly arithmetic

Description

This module performs simple arithmetic of a time series and one timestep with the same month of year. For each field in infile1 the corresponding field of the timestep in infile2 with the same month of year is used. The input files need to have the same structure with the same variables. Usually infile2 is generated by an operator of the module YMONSTAT.

Usage

cdo_ymonadd(ifile1, ifile2, ofile = NULL)

cdo_ymondiv(ifile1, ifile2, ofile = NULL)

cdo_ymonmul(ifile1, ifile2, ofile = NULL)

cdo_ymonsub(ifile1, ifile2, ofile = NULL)

Arguments

ifile1, ifile2	Strings with the path to the input files.
ofile	String with the path to the output file.

Details

ymonadd  Add multi-year monthly time series
         Adds a time series and a multi-year monthly time series.
ymonsub  Subtract multi-year monthly time series
         Subtracts a time series and a multi-year monthly time series.
ymonmul  Multiply multi-year monthly time series
         Multiplies a time series with a multi-year monthly time series.
ymondiv  Divide multi-year monthly time series
         Divides a time series by a multi-year monthly time series.

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.
