The output files will be named <obase><yyyy><suffix> where yyyy will be the year and suffix is the filename extension derived from the file format.
cdo_intyear(ifile1, ifile2, years = NULL, obase = NULL)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.
