R-ggplot2 geom_bar（）无法正确绘制列的值

Question

I am new to R

I would like plot using ggplot2 's geom_bar() :

top_r_cuisine <- r_cuisine %>%
   group_by(Rcuisine) %>%
   summarise(count = n()) %>%
   arrange(desc(count)) %>%
   top_n(10)

But when I try to plot this result by:

ggplot(top_r_cuisine, aes(x = Rcuisine)) +
       geom_bar()

I get this: which doesn't represent the values in top_r_cuisine . Why?

EDIT: I have tried:

Answer 1

c_count=c(23,45,67,43,54)
country=c("america","india","germany","france","italy")
# sample Data frame #
finaldata = data.frame(country,c_count)
ggplot(finaldata, aes(x=country)) +
geom_bar(aes(weight = c_count))

you need to assign the weights in the geom_bar()
