In the function pca.segments.2D there seems to be an error when using .text = TRUE. It seems that p is overwritten by geom_text (p <- geom_text()) instead of modified (p <- p + geom_text()).
In the function geneUsage there seems to be a mistake in case of the joint gene distribution. For the part of gencols, the do.call function should contain cbind instead of rbind.
