arithc: Arithmetic with a constant

In rcdo: Wrapper of 'CDO' Operators

Arithmetic with a constant

Description

This module performs simple arithmetic with all field elements of a dataset and a constant. The fields in outfile inherit the meta data from infile.

Usage

cdo_addc(ifile, c = NULL, ofile = NULL)

cdo_divc(ifile, c = NULL, ofile = NULL)

cdo_maxc(ifile, c = NULL, ofile = NULL)

cdo_minc(ifile, c = NULL, ofile = NULL)

cdo_mulc(ifile, c = NULL, ofile = NULL)

cdo_subc(ifile, c = NULL, ofile = NULL)

Arguments

ifile	String with the path to the input file.
c	FLOAT - Constant
ofile	String with the path to the output file.

Details

addc  Add a constant
      o(t,x) = i(t,x) + c
subc  Subtract a constant
      o(t,x) = i(t,x) - c
mulc  Multiply with a constant
      o(t,x) = i(t,x) * c
divc  Divide by a constant
      o(t,x) = i(t,x) / c
minc  Minimum of a field and a constant
      o(t,x) = min(i(t,x), c)
maxc  Maximum of a field and a constant
      o(t,x) = max(i(t,x), c)

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.
