Supports Isodat (.dxf, .cf, .did, .caf, .scn), IonOS (.iarc), LyticOS (.larc), Callisto (.bch), and Qtegra (.imexp) file formats. Provides a consistent data structure together with tools to aggregate, convert signal units, filter, and visualize the extracted data. The approach is described in Kopf et al. (2021) <doi:10.21105/joss.02878>.https://github.com/r-universe/isoverse/actions/runs/38139683272Mon, 07 Sep 2026 18:37:18 GMTisoreader20.7.0successhttps://isoverse.r-universe.devhttps://github.com/isoverse/isoreader2functionality_guide.Rmdfunctionality_guide.htmlFunctionality Guide2026-06-09 19:34:042026-08-14 12:39:40sebastian.kopf@colorado.edu (Sebastian Kopf)Easily create overlapping grammar of graphics plots for scientific data visualization.
