设置reference_map=TRUE时tract_choropleth报错，其他层级可正常运行

尝试创建带底图的纽约州人口普查区（census tract）choropleth，运行以下代码：

library(choroplethr)
library(choroplethrMaps)
library(choroplethrZip)
library(ggmap)

data(df_pop_ny_tract)
tract_choropleth(df_pop_ny_tract, state_name="new york", num_colors=1, reference_map=TRUE)

报错信息 #

Error in if (lon < -180 || lon > 180) cli::cli_abort("Longitude of center must be between -180 and 180 degrees. Note {.pkg ggmap} uses lon/lat, not lat/lon."): missing value where TRUE/FALSE needed

已验证的正常运行场景 #

• 完成Google注册并配置后，state、county、zip层级的choropleth设置reference_map=TRUE均可正常生成带底图的可视化，例如zip层级示例代码：

library(choroplethr)
library(choroplethrMaps)
library(choroplethrZip)
library(ggmap)

data(df_pop_zip)
zip_choropleth(df_pop_zip, state_zoom=c("new york"), num_colors=1, reference_map=TRUE)

• 当设置reference_map=FALSE时，tract_choropleth可正常运行，无报错。
