dhourstat: Multiday hourly statistics

In rcdo: Wrapper of 'CDO' Operators

Multiday hourly statistics

Description

This module computes statistical values of each hour of day. Depending on the chosen operator the minimum, maximum, range, sum, average, variance or standard deviation of each hour of day in infile is written to outfile. The date information in an output field is the date of the last contributing input field.

Usage

cdo_dhouravg(ifile, ofile = NULL)

cdo_dhourmax(ifile, ofile = NULL)

cdo_dhourmean(ifile, ofile = NULL)

cdo_dhourmin(ifile, ofile = NULL)

cdo_dhourrange(ifile, ofile = NULL)

cdo_dhourstd(ifile, ofile = NULL)

cdo_dhourstd1(ifile, ofile = NULL)

cdo_dhoursum(ifile, ofile = NULL)

cdo_dhourvar(ifile, ofile = NULL)

cdo_dhourvar1(ifile, ofile = NULL)

Arguments

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

Details

dhourmin    Multi-day hourly minimum
            o(01,x) = min\{i(t,x), day(i(t)) = 01\}
                             ...
            o(24,x) = min\{i(t,x), day(i(t)) = 24\}
dhourmax    Multi-day hourly maximum
            o(01,x) = max\{i(t,x), day(i(t)) = 01\}
                             ...
            o(24,x) = max\{i(t,x), day(i(t)) = 24\}
dhourrange  Multi-day hourly range
            o(01,x) = range\{i(t,x), day(i(t)) = 01\}
                             ...
            o(24,x) = range\{i(t,x), day(i(t)) = 24\}
dhoursum    Multi-day hourly sum
            o(01,x) = sum\{i(t,x), day(i(t)) = 01\}
                             ...
            o(24,x) = sum\{i(t,x), day(i(t)) = 24\}
dhourmean   Multi-day hourly mean
            o(01,x) = mean\{i(t,x), day(i(t)) = 01\}
                             ...
            o(24,x) = mean\{i(t,x), day(i(t)) = 24\}
dhouravg    Multi-day hourly average
            o(01,x) = avg\{i(t,x), day(i(t)) = 01\}
                             ...
            o(24,x) = avg\{i(t,x), day(i(t)) = 24\}
dhourstd    Multi-day hourly standard deviation
            Normalize by n.
            
            o(01,x) = std\{i(t,x), day(i(t)) = 01\}
                             ...
            o(24,x) = std\{i(t,x), day(i(t)) = 24\}
dhourstd1   Multi-day hourly standard deviation (n-1)
            Normalize by (n-1).
            
            o(01,x) = std1\{i(t,x), day(i(t)) = 01\}
                             ...
            o(24,x) = std1\{i(t,x), day(i(t)) = 24\}
dhourvar    Multi-day hourly variance
            Normalize by n.
            
            o(01,x) = var\{i(t,x), day(i(t)) = 01\}
                             ...
            o(24,x) = var\{i(t,x), day(i(t)) = 24\}
dhourvar1   Multi-day hourly variance (n-1)
            Normalize by (n-1).
            
            o(01,x) = var1\{i(t,x), day(i(t)) = 01\}
                             ...
            o(24,x) = var1\{i(t,x), day(i(t)) = 24\}

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.
