我可以使用什么 function 来限制 geom_bar plot 中的 y 轴？

Question

I am new to R and making a very simple histogram, however the range of my y-axis is too large and greatly limits visibility of the graph. I have tried using ylim however I get the error "Error in discrete_scale(c("x", "xmin", "xmax", "xend"), "position_d", : unused argument (ylim = c(0, 75))"

Here is the code used to make the histogram:

recipes %>%
mutate(ingredient = fct_infreq(ingredient)) %>%
ggplot(aes(x = ingredient)) +
geom_bar() +
scale_x_discrete(labels = NULL)

Any help and suggestions would be greatly appreciated.

Answer 1

you seem to have a wrong sintax in ylim. Try with:

recipes %>%
mutate(ingredient = fct_infreq(ingredient)) %>%
ggplot(aes(x = ingredient)) +
geom_bar() +
scale_x_discrete(labels = NULL) +
ylim(0, 75)
