timcor: Correlation over time

In rcdo: Wrapper of 'CDO' Operators

Correlation over time

Description

The correlation coefficient is a quantity that gives the quality of a least squares fitting to the original data. This operator correlates each gridpoint of two fields over all timesteps. If there is only one input field, the p-value (probability value) is also written out. With S(x) = {t, i_1(t,x) != missval and i_2(t,x) != missval} it is o(1,x) = Cor{(i_1(t,x), i_2(t,x)), t_1 < t <= t_n} For every gridpoint x only those timesteps t belong to the sample, which have i_1(t,x) != missval and i_2(t,x) != missval.

Usage

cdo_timcor(ifile1, ifile2, ofile = NULL)

Arguments

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

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.
