[R] text annotation on Manhattn plot in qqman

[Ana Marija]

Hello,

I am making manhattan plot with:
library(qqman)
manhattan(a, chr="CHR", bp="BP", snp="SNP", p="P",annotatePval = 0.0001)

and I would like to annotate these two SNPs which are above the
threshold so that they have GENE name beside them:

> a[a$SNP=="rs4081570",]
        SNP            P CHR       BP GENE
1 rs4081570 6.564447e-05  19 15918647 UCA1
> a[a$SNP=="rs11867934",]
            SNP            P CHR       BP GENE
1021 rs11867934 6.738066e-06  17 16933404 FLCN

Right now my plot only has SNP name for those 2, how to add GENE names
(FLCN and UCA1 as well)

Please advise
Ana
