geom_jitter(size = 6.5)+
ggtitle("The Actual Long, Normal Title of Titliness")+
theme(plot.title = element_text(hjust = 0,face = "bold", size = 30),
      axis.ticks = element_blank(),
      legend.text = element_text(size = 25),
      axis.title = element_text(size = 25, face = "bold"),
      axis.text = element_text(size = 25, vjust = 0.05),
      legend.position = "bottom", 
      plot.margin = unit(c(4, 3, 1, 1), "lines"))
p
grid.text('A', x = unit(0.1, 'npc'), y = unit(.90, 'npc'), gp = gpar(fontsize=28))
