The header information in infile1 have to be the same as in infile2. Usually infile2 is generated by an operator of the module YEARSTAT.

Usage

cdo_yearadd(ifile1, ifile2, ofile = NULL)

cdo_yeardiv(ifile1, ifile2, ofile = NULL)

cdo_yearmul(ifile1, ifile2, ofile = NULL)

cdo_yearsub(ifile1, ifile2, ofile = NULL)

Arguments

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