Either "last", or the segment number.} \item{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.} \item{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.} \item{windows}{Numeric vector of width of moving windows in days, for calculating maximum time weighted average concentrations and areas under the curve.} \item{thresholds}{Numeric vector of threshold concentrations in \u00B5g/L for generating event statistics.} } \value{ An instance of an R6 object of class \code{\link{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). } \examples{ H_sw_D4_pond <- read.TOXSWA_cwa("00001p_pa.cwa", basedir = "SwashProjects/project_H_sw/TOXSWA", zipfile = system.file("testdata/SwashProjects.zip", package = "pfm")) } \author{ Johannes Ranke }
