read.TOXSWA_cwa. pfm 0.3-7

Usage

read.TOXSWA_cwa(filename, basedir = ".", zipfile = NULL, segment = "last", substance = "parent", total = FALSE, windows = NULL, thresholds = NULL)

Arguments

filename: The filename of the cwa file (TOXSWA 2.x.y or similar) or the -out file (FOCUS TOXSWA 4, i.e. TOXSWA 4.4.2 or similar).
basedir: The path to the directory where the cwa file resides.
zipfile: Optional path to a zip file containing the cwa file.
segment: The segment for which the data should be read. Either "last", or -the segment number.
substance: For TOXSWA 4 .out files, the default value "parent" leads -to reading concentrations of the parent compound. Alternatively, the substance -of interested can be selected by its code name.
total: Set this to TRUE in order to read total concentrations as well. This is -only necessary for .out files as generated by TOXSWA 4.4.2 or similar, not for .cwa -files. For .cwa files, the total concentration is always read as well.
windows: Numeric vector of width of moving windows in days, for calculating -maximum time weighted average concentrations and areas under the curve.
thresholds: Numeric vector of threshold concentrations in µg/L for -generating event statistics.

Value

- -

-An instance of an R6 object of class -TOXSWA_cwa. -

- -

Description

- -

Read TOXSWA hourly concentrations of a chemical substance in a specific -segment of a TOXSWA surface water body. Per default, the data for the last -segment are imported. As TOXSWA 4 reports the values at the end of the hour -(ConLiqWatLayCur) in its summary file, we use this value as well instead -of the hourly averages (ConLiqWatLay).

-                                 basedir = "SwashProjects/project_H_sw/TOXSWA",
-                                 zipfile = system.file("testdata/SwashProjects.zip",
-                                                       package = "pfm"))
