Differential expression results: between-group comparison of contrasts
Source:R/de_interaction_results.R
de_interaction_results.RdDESeq2 interaction results that test whether the change from monocytes to in vitro differentiated dendritic cells (moDC or tolDC) is different in SLE patients than in healthy controls. Used in the lesson about the between-group comparison of contrasts (l7_DEGs_between_groups_es; Figure 7A and 7B of the article).
Format
A named list with two data frames (moDC and tolDC),
each with 21,718 rows (genes) and 7 columns: gene, baseMean,
log2FoldChange, lfcSE, stat, pvalue and
padj (see de_results).
Source
Generated from filtered_txi and metadata_cleaned.
Details
Design (all genes of filtered_txi, the 99 samples, reference levels
Ctrl and monocyte): ~ Group + Cell_type + Group:Cell_type.
Results were extracted with results(alpha = 0.05, name =
"GroupSLE.Cell_type<moDC|tolDC>") (Wald test, Benjamini-Hochberg adjustment).
The log2FoldChange is a difference of differences:
(dendritic cell vs monocyte in SLE) minus (dendritic cell vs monocyte in Ctrl).
With padj < 0.05 (up / down): moDC 1 / 28 and
tolDC 3 / 38. The script that generates this object is
data-raw/lesson7_checkpoints.R.
