With rbms, we aim to facilitate the implementation of statistical and mathematical methods developed for computing relative abundance indices from yearly time-series of butterfly counts. These data are characterised by temporal patterns (phenology) that must be accounted for when deriving abundance from a time-series of counts. As a toolbox, we plan to implement more methods to compute and visualise metrics as they develop. The rbms package will provide the option of being coupled and work in line with other tools available and developed by the community (e.g. rtrim, BRCindicators). With the development of the ‘rbms’ R package, we also provide a tutorial to facilitate its usage and understanding.

Although rbms implements methods that were developed independently and for which the source should be cited, users should also cite the rbms package and its version to ensure appropriate referencing and improve the reproducibility of the work.

Suggested citation for the rbms package

Installation

Once the R programming system is successfully installed, you can install the rbms package from GitHub. For this you will need to install the package devtools or remotes, both available on CRAN. Once installed, use the function devtools::install_github() to install the rbms package on your system.

Note that rbms is build with R > 3.6.0, so you might need to update your R system before installation. To install devtools on Windows system, you will also need to install Rtools - note Rtools40 for R 4.x.x New to R or want to refresh your R coding skills, try the excellent tutorials available at ourcodingclub 👍

if(!requireNamespace("devtools")) install.packages("devtools")
devtools::install_github("RetoSchmucki/rbms")

Get Started

Consult the tutorial vignettes / Articles to learn about rbms data format and the workflow how to compute flight curves, abundance indices, and collated index with a bootstrap confidence interval

Further documentation is also available through the help function in R or from the rbms online references
