Overlapping axis labels in R [duplicate]

Answer 1

You can tune a bit your x axis either by automatically abbreviating labels as in

p + scale_x_discrete(labels = abbreviate)

or you can provide abbreviated labels yourself as in

p + scale_x_discrete(labels = c("Congenital Rubella" = "C. Rub.", ..., "Total tetanus" = "T. tet.", "Yellow fever" = "Y. fever")
