Return QC plots

get_dge_qc_plot.Rd

Getter function to extract the QC plots from the BulkDge() class. These are added when you run for example qc_bulk_dge() and normalise_bulk_dge(). You can either leave the plot choice as NULL and provide input when prompted, or you provide the name. The possible plots that might be in the class

  • p1_nb_genes_cohort Proportion of non-zero genes for the samples in the respective cohorts (added after using qc_bulk_dge()).

  • p2_outliers An outlier plot based on the data from p1, added after using qc_bulk_dge().

  • p3_voom_normalization Initial Voom normalisation plot after filtering lowly expressed genes. Added after using normalise_bulk_dge().

  • p4_boxplot_normalization Expression levels after normalisation. Added after using normalise_bulk_dge().

  • p5_pca_case_control A PCA plot with the chosen case control category. Added if calculate_pca_bulk_dge() is run.

  • p6_batch_correction_plot A PCA plot pre and post batch correction with the case-control category overlayed. Added if batch_correction_bulk_dge() is run.
