The MRSea package was developed for analysing data that was collected for assessing potential impacts of renewable developments on marine wildlife, al- though the methods are applicable to other studies as well. This user guide consists of three sections following this introduction.
We present two worked examples of which one is segmented line transect data (offshore scenario, Chapter 2) and one is grid count data (nearshore scenario, Chapter 3). Both examples are simulated data based on actual studies. The type of impact artificially imposed for these data sets was a redistribution of animals within the study area and the data are included in the package. The package also includes additional datasets simulated under no impact and overall decrease scenarios. All the coding necessary to reproduce the worked examples is given in the respective sections.
Following these examples, Chapter 4 provides extra tips and tricks for coding in R that might be useful in case the user needs to adjust the code for their own purposes.
A full description of each of the functions within the MRSea package can be found in the reference manual at: http://creem2.st-and.ac.uk/software.aspx. The manual and this document use version 0.1.1 of MRSea.
