Creates a Value Function for Ecological River Assessment

Description

Translates a Word Given a Dictionary

Description

Translates a word given as the first argument using a dictionary provided as the second argument of the function. The dictionary consists of a character vector of translated words labelled by the words in the original language. If no translation is found, the given word in the original language is returned.

Usage

ecoval.translate(word,dictionary)

Arguments

word

A single word to be translated.

dictionary

Vector of translated words labelled by the words in the original language.

Value

The function returns the translated word.

Examples

ecoval.translate("x",c(x="X",y="Y",z="Z"))

Aggregate valuations along a single spatial dimension.

Description

Aggregate valuations of different lake shore sections along a single spatial dimension according to an arbitrarily defined grid.

Usage

lake.morphol.2016.aggregate.val.spatial(u,breakpoints)

Arguments

u

Data frame with calculated values for nodes (columns) and different shore sections (rows). The row labels are assumed to contain the spatial information as a string in the format id | start - end where id is the id of the lake, start is the start coordinate of the section along the shore line, and end is the end coordinate along the shore line. The first part, id | , is optional and can be omitted if the data is from a unique length measurement (of a single lake). Single spaces between the items are required. Note that this format is produced automatically when reading attributes with the function lake.morphol.2016.read.attrib and is then transferred to the values file when evaluating the value function.

breakpoints

For a single lake id, a vector of breakpoints that define the intervals to which the values are aggregated. For multiple lakes, a list of such vectors with as many elements and in the same order as the lake ids in the data frame provided with the argument u.

Details

Aggregation is done by length-weighted averaging of the values at each level of the objectives hierarchy. Note that this leads to an valuation result that is not compatible with the original value function (valuations of end nodes and aggregated nodes) across the objective hierarchy. Nevertheless, this seems to be the most meaningful aggregation as we cannot average discrete, non-numeric attributes and then re-calculate the corresponding values.

Value

A data frame of the same format as the argument u with the aggregated values.

Reads attributes with different segmentation.

Description

Reads individual attributes with different segmentation and combines them to a data frame with unified segmentation.

Usage

lake.morphol.2016.read.attrib(directory    = ".",
                              language     = "English",
                              dictionaries = NA,
                              attrib.names = NA,
                              col.names    = NA)

Arguments

directory

(optional) Directory from which the files are read. The directory must contain the data files, one file per attribute. The file names must start with the attribute names as given by the argument attrib.names and they must contain the columns as specified by the argument col.names. The file format must be comma-separated text with the first row containing the headers as specified by the argument col.names and subsequent rows the corresponding data. The files may contain additional columns that will be ignored.

language

Language to be used to denote nodes, attributes and attribute levels. Must be a column name of the table provided by the second argument.

dictionaries

attrib.names

(optional) Names of the attributes. These should match first characters of the names of the files that provide the corresponding data. NA indicates that the attribute names are taken from the dictionary. Order of the names is E01, E02, B02, B01, C06, C01, C02, C03, C04, C05, D01, D02.

col.names

(optional) Names of the columns to be read from the individual attribute files. The first three elements must be present and represent the columns containing the start and end point of the reach (one dimenstional length measure along the shoreline) and the corresponding attribute level. The fourth element represents an optional id to distinguish different lakes or shoreline measures (for the same id, the lenght measure used to characterize start and end of a reach must be unique). This element can be missing or NA; both indicates a unique lenght measure across all records. Further column names can be provided and are interpreted as comments. These are merged to a single string when compiling the output data frame. col.names = NA indicates that the names form the dictionary are used.

Value

Creates a Value Function for River Micropollutants

Description

Creates a value function for river micropollutants with episodic inputs (pesticides, often from diffuse sources) and continous inputs (mainly from point-sources). Micropollutants with continous inputs are assessed regarding their toxicity to different organism groups. Micropollutants with episodic inputs are grouped according to their mode of action while exposure patterns are taken into account.

Usage

val.micropoll.create(language     = "English",
                     dictionaries = NA,
                     col          = "black")

language

Language to be used to denote nodes, attributes and attribute levels. Must be a column name of the table provided by the second argument.

dictionaries

col

Color of bounding boxes in objectives hierarchy.
