R - ggplot2 geom_bar（）没有正确绘制列的值

I am new to R

我是R的新手

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

我想用ggplot2的geom_bar（）进行绘图：

top_r_cuisine <- r_cuisine %>%

   arrange(desc(count)) %>%
   top_n(10)

但是，当我尝试通过以下方式绘制此结果：

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

#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()

你需要在geom_bar中分配权重（）
