Fixed now, thanks!

The latest dev version can be installed using: devtools::install_github("kassambara/ggpubr")

library(ggpubr)
# Set y ticks step
# Use this
gghistogram(iris, x = "Sepal.Length", fill = "lightgray",
            yticks.by = 2)

# Or this
gghistogram(iris, x = "Sepal.Length", fill = "lightgray") +
  scale_y_continuous(breaks = get_breaks(by = 2, from = 0))
