Introducing the signgloss R Package (2022)

Abstract: The signglossR package is a library written in the programming language R, intended as an easy-to-use resource for those who work with signed language data and are familiar with R. The package contains a variety of functions designed specifically towards signed language research, facilitating a single-pipeline workflow with R when accessing public language resources remotely (online) or a user’s own files and data. The package specifically targets processing of image and video files, but also features some interaction with software commonly used by researchers working on signed language and gesture, such as ELAN and OpenPose. The signglossR package combines features and functionality from many other libraries and tools in order to simplify and collect existing resources in one place, as well as adding some new functionality, and adapt everything to the needs of researchers working with visual language data. In this paper, the main features of this package are introduced.

## 1 figure 3 : producing an overlay image from two images with a 25% opacity "ghost" outline for the first image. this can be achieved directly when downloading a file from the dictionary using the following function call: > get_image(1241, @xmath0 this creates the following output, which can be useful as it takes up less horizontal space and illustrates the dynamic movement in a single frame -see figure 4 . additionally, the functions get video() and get gif() can download a sign as video (.mp4) or gif (.gif) directly:
