Changes inspectdf dependency removed: inspectdf was archived from CRAN on 2026-04-10, which made the package impossible to install from a clean library (any dependency resolution against the CRAN source index, e.g. pak in GitHub Actions, failed with "Can't find package called inspectdf") New plot_na_percentage(): bar plot with the percentage of NA values per column, computed with naniar::miss_var_summary() (naniar was already a dependency). It replaces the inspectdf::inspect_na() %>% show_plot() chart in the metabolomics, olink, and proteomics QC plots, producing the same chart (same values, column order, and text labels) Bug Fixes Olink QC plots failed with ggplot2 4.0: the id-count plots of plot_basic_olink_qc() labelled the bars with aes(label = n) instead of olink_count, so ggplot2 resolved n to a function. ggplot2 4.0 rejects that ("Aesthetics are not valid data columns"), so the olink QC plots failed for any dataset with 200 samples or fewer Tests Unit tests for plot_na_percentage() and end-to-end tests of plot_basic_metabolomics_qc() (bundled data) and plot_basic_olink_qc() (synthetic data) writing the QC pdfs
