D6recaptureR

The goal of D6recaptureR is to help us during swallow recapturing

Installation

You can install the development version of D6recaptureR from GitHub with:

# install.packages("devtools")
devtools::install_github("mariusgrabow/D6recaptureR")

Example

This is a basic example which shows you how to handle a recapture:

1. You need a dataframe named cmr (case-sensitive) from the last years (provided by Marius). Here, we will work with one example from one bird (included in the package)

Please note: In this example, cmr has 11 rows

library(D6recaptureR)

cmr<-D6recaptureR::cmr_filter
nrow(cmr)
#> [1] 11

Imagine you recaptured bird (VH59051) and would like to know the capture history:

(You can write vh59051 or VH59051, the package corrects to Uppercase)

#> observation was added into global environment. cmr hat 1 more row now

Please note, cmr has 12 rows now (one was added with the System date & time)

nrow(cmr)
#> [1] 12

Let’s look at the last observation, which we just added. Here, there is data missing, although we might collected it manually on the field sheets. However, this should save us a lot of time because we don’t have to screen a pile of paper.
