如何根据ggplot2中的某些条件删除标签？

我正在执行#duboischallenge，并且正在挑战5。

我想删除情节上的标签“ 0％”。

代码（仍在学习，可能不是最有效的代码！）：

income <- readr::read_csv('https://raw.githubusercontent.com/rfordatascience/tidytuesday/master/data/2021/2021-02-16/income.csv')


data5 <- income %>%
  gather(expenses, percentage, 3:7) %>%
  mutate(percentage = replace_na(percentage, 0))

data5$expenses <- factor(data5$expenses, levels = c("Other", "Tax", "Clothes", "Food", "Rent"))
data5$Class <-factor(data5$Class, levels = c("Over $1000", "$750-1000", "$500-750", "$400-500", "$300-400", "$200-300", "$100-200"))

plot5 <-ggplot(data5, aes(x = Class, y = percentage, fill = expenses)) +
  geom_bar(position = "fill", stat = "identity")+
  scale_fill_manual(values = c("black", "blueviolet", "darksalmon", "azure3", "cornsilk3"), breaks = c("Rent", "Food","Clothes", "Tax", "Other"))+
  geom_text(aes(x = Class, y = percentage, label = paste0(percentage, "%")), color = if_else(data5$expenses == "Rent", "white", "black"), size = 3.5, position = position_fill(vjust = 0.5)) +
  coord_flip()

如果我加

geom_text(data = data5 %>% filter(percentage > 3),aes(x = Class, y = percentage, label = paste0(percentage, "%")), color = if_else(data5$expenses == "Rent", "white", "black"), size = 3.5, position = position_fill(vjust = 0.5))

我收到此错误：错误：美学必须为长度1或与数据（32）相同：颜色

如何删除“ 0％”标签？
