In rcdo: Wrapper of 'CDO' Operators

Arithmetic with days

Description

This module multiplies or divides each timestep of a dataset with the corresponding days per month or days per year. The result of these functions depends on the used calendar of the input data.

Usage

cdo_divdpm(ifile, ofile = NULL)

cdo_divdpy(ifile, ofile = NULL)

cdo_muldpm(ifile, ofile = NULL)

cdo_muldpy(ifile, ofile = NULL)

Arguments

ifile	String with the path to the input file.
ofile	String with the path to the output file.

Details

muldpm  Multiply with days per month
        o(t,x) = i(t,x) * days_per_month
divdpm  Divide by days per month
        o(t,x) = i(t,x) / days_per_month
muldpy  Multiply with days per year
        o(t,x) = i(t,x) * days_per_year
divdpy  Divide by days per year
        o(t,x) = i(t,x) / days_per_year

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.
