Question

嘿，我一直在努力用我的数据集重新创建与此类似的图： https://twitter.com/thomasp85/status/1036915662025895936?lang=en

我无法用令人讨厌的reprex重现错误，但是错误消息是这样的：

sprintf（paste0（“％0”，nc，“ i”），frame）中的错误：格式'％0NA'无效；对数字对象使用％f，％e，％g或％a格式

这是我以前从未处理过的错误，感谢您的帮助

df <- structure(list(long = c(23.9665031433105, 23.9665031433105, 23.9665031433105, 
23.9665031433105, 23.9665031433105, 23.9665031433105), lat = c(-10.8717775344849, 
-10.8717775344849, -10.8717775344849, -10.8717775344849, -10.8717775344849, 
-10.8717775344849), group = c(3, 3, 3, 3, 3, 3), region = structure(c(2L, 
2L, 2L, 2L, 2L, 2L), .Label = c("Algeria", "Angola", "Benin",

1972, 1973, 1974, 1975), rate = c(NA_real_, NA_real_, NA_real_, 
NA_real_, NA_real_, NA_real_), pop = c(31787566, 31787566, 31787566, 
31787566, 31787566, 31787566), subregion = c("Middle Africa", 
"Middle Africa", "Middle Africa", "Middle Africa", "Middle Africa", 
"Middle Africa")), row.names = c(NA, 6L), class = "data.frame")

ggplot(df, aes(x = year, y = rate, group = region)) + 
    geom_line() + geom_segment(aes(xend = 2018, yend = rate)) + 
    geom_point() + transition_reveal(year) + ease_aes("linear")
#> Error in ggplot(uis_final_line, aes(x = year, y = rate, group = region)): could not find function "ggplot"

^{由reprex package（v0.2.1）于2019-01-23创建}

如何更改gganimate的数字格式，以免产生sprintf错误？
