# Read TOXSWA surface water concentrations
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). In TOXSWA 5.5.3 this
variable was renamed to ConLiqWatLay in the out file.
## Usage
``` r
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
when using FOCUS TOXSWA 4 (i.e. TOXSWA 4.4.2) or higher.
- 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 .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`](https://pkgdown.jrwb.de/pfm/reference/TOXSWA_cwa.md).
## Author

## Examples
``` r
H_sw_D4_pond <- read.TOXSWA_cwa("00001p_pa.cwa",
basedir = "SwashProjects/project_H_sw/TOXSWA",
zipfile = system.file("testdata/SwashProjects.zip",
package = "pfm"))
