In NoonanM/HRcorrect: HRcorrect

HRcorrect

A shiny app for correcting previously estimated 95\% home range areas derived from conventional estimators for body-mass specific bias.

The correction is based on the regressional analyses in Noonan et al. (2019) Body size dependent underestimation of home range areas. In prep.

This correction is not a substitute for using a more rigorous home range estimator (e.g. autocorrelated-KDE), and should only be used for cases where the underlying tracking data are not accessible.

The app can be used online at:

https://hrcorrect.shinyapps.io/HRcorrect/

Or locally, via an R installation. To install and run the app run the following lines in R:

```{r, echo=FALSE, message=FALSE, warning = FALSE}

Get list of the currently installed packages

avail <- installed.packages()[, 1]

Make a list of the required packages

needed <- c("shiny", "shinydashboard", "devtools")

Check which of these are missing

install <- needed[!needed %in% avail]

And then install them if necessary

if (length(install) > 0) { install.packages(install) }

After installing the dependencies,

install HRcorrect from the github repository

devtools::install_github(repo = "NoonanM/HRcorrect")

Finally, run the application

correct()

```

Notes:

The area correction is unit invariant, and will preserve whatever units the original area are provided in.

Mass must be provided in kilograms.

Upon installation, the HR_Correction() function is exported into the namespace and can be used directly in the command line interface.
