The repertory grid technique (often abbreviated as grid or repgrid) is a person-centered data collection method. It is primarily used in clinical psychology and generates a mix of qualitative and quantitative data. The OpenRepGrid.ic R package presented here is a browser-based software to perform Interpretive Clustering (IC) for such data. IC is a method for clustering the attributes (so called constructs) resulting from a repertory grid interview by finding relational patterns between them. The IC method is described in detail in our recent publication (Burr et al., 2020). The package is part of the OpenRepgrid project, which contains several software packages for the analysis of repertory grid data. In the following, we will briefly describe the repertory grid technique and provide a short example of how a grid dataset can be analyzed and interpreted using our OpenRepGrid.ic software.
