geom_text() with overlapping labels

Question

So some labels of my scatterplot overlap. I have tried using direct.label with the method "smart.grid", but it does not yield appropiate results. Here's my current graph:

The code that generates it:

ggplot(d, aes(x=ILE2, y=TE,label=d$CA)) +
  geom_point(mapping=aes(x=ILE2, y=TE, fill=d$CA), size=9, shape=20, color="black") +
  geom_text(data = d,mapping=aes(x=ILE2, y=TE,label=d$CA), size=4, vjust=3, hjust=0.5,size=6)+
  geom_smooth(method=lm,se=F)+
  theme(legend.position = "none")+
  ggtitle("Tasa de Empleo según Índice de Libertad Económica") +
  labs(x="Índice de Libertad Económica",y="Tasa de Empleo") + 
  theme(plot.title = element_text(family =windowsFonts(Times=windowsFont("TT Times New Roman")), color="#666666", face="bold", size=22, hjust=0.5)) +
  theme(axis.title = element_text(family =windowsFonts(Times=windowsFont("TT Times New Roman")), color="#666666", face="bold", size=22)) 

The data:

structure(list(CA = structure(c(1L, 2L, 3L, 4L, 6L, 8L, 9L, 5L,

Answer 1

You might consider trying ggrepel to place your labels without overlaps.

library(ggrepel)
ggplot(d, aes(x=ILE2, y=TE,label=d$CA)) +
  geom_point(mapping=aes(x=ILE2, y=TE, fill=d$CA), size=9, shape=20, color="black") +
  geom_text_repel(
    data = d,
    mapping=aes(x=ILE2, y=TE,label=d$CA),
    size=4, size=6, box.padding = unit(0.5, "lines")
  )+
  geom_smooth(method=lm,se=F)+
  theme(legend.position = "none")+
  ggtitle("Tasa de Empleo según Índice de Libertad Económica") +
  labs(x="Índice de Libertad Económica",y="Tasa de Empleo")
