The "guide to creating design matrices for gene expression experiments" of the [RNAseq123 workflow][1] doesn't show some figures.
Figure 3 and figure 13 show the html code to include the figure but not the actual figure.
In addition, There is along line of text formatted as inline code that starts with "Figures (see ?stats::model.matrix' for more). PLOT: Observed data points are drawn".
I think a plot was meant to go there and that there is a missing ` after matrix instead of '.
I couldn't find the original repository to send a PR to fix this.
Cool. Thanks for looking into it.
