I used width=0.5, to reduce bar widths and aspect.ratio = 2/1 to
reduce white spaces between bars but now text on my x axis is
overlapping and my plot is too elongated, and I don't have those 3
vertical lines trough bars.
Please advise
p<-ggplot(data=toplot, aes(x=cat, y=props)) +
geom_bar(stat="identity",width=0.5, fill="steelblue")+
geom_errorbar(aes(ymin=props-1.96*ses, ymax=props+1.96*ses), width=.1,
position=position_dodge(.9)) +
geom_signif(comparisons=list( c("All eQTL", "eQTL from 103 genes"),
c("All SNPs", "eQTL from 103 genes")),
y_position=c(0.065, 0.07), tip_length=0, annotation=c("p
= 0.0012", "p = 0.0023")) +
scale_y_continuous(breaks=seq(0,.06,by=.01)) +
xlab("") + ylab("Proportion p-values < 0.05") +
theme(aspect.ratio = 2/1,axis.title.x=element_text(size=1,face="bold"))
p
