【问题描述】：

我正在尝试制作以下数据的动画累积地图：

structure(list(station_install_date = structure(c(16684, 16684, 
16684, 16684, 16684, 16684), class = "Date"), lat = c(37.548645, 
37.549561, 37.550007, 37.550629, 37.552746, 37.554951), long = c(126.912827, 
126.905754, 126.914825, 126.914986, 126.918617, 126.910835), 
    capa_sum = c(10L, 5L, 5L, 13L, 10L, 14L)), row.names = c(NA, 
-6L), groups = structure(list(station_install_date = structure(c(16684, 
16684, 16684, 16684, 16684, 16684), class = "Date"), lat = c(37.548645, 
37.549561, 37.550007, 37.550629, 37.552746, 37.554951), .rows = structure(list(
    1L, 2L, 3L, 4L, 5L, 6L), ptype = integer(0), class = c("vctrs_list_of", 
"vctrs_vctr", "list"))), row.names = c(NA, -6L), class = c("tbl_df", 
"tbl", "data.frame"), .drop = TRUE), class = c("grouped_df", 
"tbl_df", "tbl", "data.frame"))

我的代码如下：

seoul <- get_googlemap("Seoul, South Korea", zoom=11, maptype = "roadmap")
ggmap(seoul) + 
  geom_point(data = install_time_df, aes(x = long, y = lat), color = "red", alpha = 0.3) +
  transition_time(station_install_date) +
  ease_aes("linear")

但是，我不断收到错误消息：

Error in seq.default(range[1], range[2], length.out = nframes) : 
  'from' must be a finite number

【解决方案1】：

试试：

p2<- ggmap(seoul) + 
  geom_point(data = install_time_df, aes(x = long, y = lat), color = "red", alpha = 0.3) +
  transition_manual(station_install_date, cumulative = TRUE) +
  ease_aes("linear")

anim2<- animate(p2, renderer = gifski_renderer())
anim_save("C:\\Users\\82104\\Desktop\\따릉이\\anim2.gif", animation = anim2)
