[R] Annotation Ticks on the axis

Hi

Yes that is exactly from where I found sec_axis  example.

ggplot(mpg, aes(displ, hwy)) +
  geom_point() +
  scale_y_continuous(
    "mpg (US)",
    sec.axis = sec_axis(~ . * 1.20, name = "mpg (UK)")
  )

which works if used as intended

p1<-ggplot(df,aes(x,y))+geom_point()+
 scale_x_log10(
    breaks = scales::trans_breaks("log10", function(x) 10^x),
    labels = scales::trans_format("log10", scales::math_format(10^.x))
  ) +
  scale_y_log10(
    breaks = scales::trans_breaks("log10", function(x) 10^x),
    labels = scales::trans_format("log10", scales::math_format(10^.x)),
    sec.axis = sec_axis(~./500)
  ) +theme_bw()
p2<-p1 + annotation_logticks()
p2

Cheers
Petr
