Hi all,

I'm experiencing difficulty implementing the highlight.gr argument within the plotGrandlinear function of ggbio. I'm trying to highlight and label significant sites from an association study. I can produce a manhattan plot, but cannot seem to get my significant points highlighted and labeled. Sample code here:

highlight_gr <- gr[which(p.adjust(alt_fit$p.value[,3],
    method = "bonferroni") < 0.05),]
mcols(gr) <- -log10(alt_fit$p.value)

plotGrandLinear(gr,
    aes(y = dxMM),
    color = c("#7fc97f", "#fdc086"),
    cutoff = -log10(0.05 / length(gr)),
    cutoff.color = "black",
    hightlight.gr = highlight_gr,
    highlight.label = TRUE,
    highlight.col = "red") +
    theme(axis.text.x=element_text(angle=-90, hjust=0))
