[R] editing plot

[Ana Marija]

HI Rui,

Thank you so much for getting back to me!
I did implement your idea (see attach):

ax.11.text <- element_text(size = 10)
ay.11.text <- element_text(size = 10)
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_classic()+
  theme(panel.grid.major.x = element_line(size = 0.1, color = "grey"),
        panel.grid.major.y = element_blank(),
        panel.grid.minor = element_blank(),axis.text.x =
ax.11.text,axis.text.y=ay.11.text
  )
p

I was wondering is there is any way to decrease the amount of white
spaces around the bars?

Thanks
Ana
