Hello,
You are almost there.
With scale_x_continuous use argument limits.
ggplot(dat = tibDat,
aes(x = x, y = y)) +
geom_point() +
scale_x_continuous(breaks = 1:6, labels = 1:6,
limits = c(1, 6))
And with xlim it's not a vector c(1, 6), it's each element on its own:
xlim(1, 6)
Or
lims(x = c(1, 6))
But with these two, the labels are not like you want them, they are 2 by 2.
Hope this helps,
Rui Barradas
