Question

library(plotly)

xdf <- read.csv("https://raw.githubusercontent.com/plotly/datasets/master/2014_us_cities.csv")

xdf$q <- with(xdf, cut(pop, quantile(pop)))

levels(xdf$q) <- paste(c("1st", "2nd", "3rd", "4th", "5th"), "Quantile")

xdf$q <- as.ordered(xdf$q)

list(
  scope = "usa", 
  projection = list(
    type = "albers usa"
  ), 
  showland = TRUE, 
  landcolor = toRGB("gray85"), 
  subunitwidth = 1, 
  countrywidth = 1, 
  subunitcolor = toRGB("white"), 
  countrycolor = toRGB("white")
) -> g

plot_geo(
  data = xdf, 
  locationmode = "USA-states", 
  sizes = c(1, 250)
) %>%
  add_markers(
    x = ~ lon, y = ~ lat, 
    size = ~ pop, color = ~ q,  
    hoverinfo = "text",
    text = ~ paste(xdf$name, "<br />", xdf$pop / 1e6, " million")
  ) %>%
  layout(
    title = "2014 US city populations<br>(Click legend to toggle)", 
    geo = g
  ) -> p

p

这是错误
