sEddyProc.new: sEddyProc$new - Initialization of sEddyProc

In REddyProc: Data processing and plotting utilities of (half-)hourly eddy-covariance measurements

Description

Creates the fields of the sEddyProc R5 reference class for processing of half-hourly eddy data

Usage

sEddyProc.new(ID.s, Data.F, ColNames.V.s, ColPOSIXTime.s = "DateTime", 
    DTS.n = 48, ColNamesNonNumeric.V.s = character(0), 
    Lat_deg.n = NA_real_, Long_deg.n = NA_real_, TimeZone_h.n = NA_integer_, 
    ...)

Arguments

ID.s	String with site ID
Data.F	Data frame with at least three month of half-hourly site-level eddy data
ColNames.V.s	Vector with selected column names, the less columns the faster the processing
ColPOSIXTime.s	Column name with POSIX time stamp
DTS.n	Daily time steps
ColNamesNonNumeric.V.s	Names of columns that should not be checked for numeric type, e.g. season column
Lat_deg.n	Latitude in (decimal) degrees (-90 to +90)
Long_deg.n	Longitude in (decimal) degrees (-180 to +180)
TimeZone_h.n	Time zone (in hours) shift to UTC, e.g. 1 for Berlin
...	('...' required for initialization of class fields)

Details

The time stamp must be provided in POSIX format, see also fConvertTimeToPosix. For required properties of the time series, see fCheckHHTimeSeries.

Internally the half-hour time stamp is shifted to the middle of the measurement period (minus 15 minutes or 30 minutes).

All other columns may only contain numeric data. Please use NA as a gap flag for missing data or low quality data not to be used in the processing. The columns are also checked for plausibility with warnings if outside range.

sID is a string for the site ID.

sDATA is a data frame with site data.

sTEMP is a temporal data frame with the processing results.

sINFO is a list containing the time series information.

DIMS

Number of data rows

DTS

Number of daily time steps (24 or 48)

Y.START

Starting year

Y.END

Ending year

Y.NUMS

Number of years

Y.NAME

Name for years

sLOCATION is a list of information on site location and timezone (see sSetLocationInfo.

sTEMP is a data frame used only temporally.

Value

Initialized fields of sEddyProc.
