r情节：交互式图：如何更改滑块的预设

我使用Plotly's Plot_Geo函数创建了一个Choropleth地图，并添加了一个滑块以在不同年份中循环。如何将滑块设置为其他默认位置？在我的示例中，我希望滑块在2005年为默认值，以便用户可以向后循环而不是向前循环。

df <- data.frame(year=c(rep(2000,5), rep(2001,5), rep(2002,5), rep(2003,5), rep(2004,5), rep(2005,5)),
                 stat=rep(c(4,5,6,7,3,4), 5),
                 location=rep(c("DEU", "BEL", "FRA", "ITA", "SWE", "FIN"),5))

plot_geo(df, frame=~year) %>% 
  add_trace(locations=~location, z=~stat, color=~stat) %>%
  layout(geo=list(scope="europe"))

I created a choropleth map using plotly's plot_geo function and added a slider to cycle through different years.
How can I set the slider to a different default position?
In my example, I would like the slider to be at 2005 as the default, so that the user can cycle backwards instead of forward.

df <- data.frame(year=c(rep(2000,5), rep(2001,5), rep(2002,5), rep(2003,5), rep(2004,5), rep(2005,5)),
                 stat=rep(c(4,5,6,7,3,4), 5),
                 location=rep(c("DEU", "BEL", "FRA", "ITA", "SWE", "FIN"),5))

plot_geo(df, frame=~year) %>% 
  add_trace(locations=~location, z=~stat, color=~stat) %>%
  layout(geo=list(scope="europe"))
