调整mapdeck描边或填充色导致R崩溃问题求助

问题描述 #

• Windows 11环境下使用mapdeck包，只要修改多边形、线或点的描边/填充颜色，R就会崩溃并需终止会话；不修改颜色时数据可正常渲染。
• 崩溃前会弹出如下警告：

Registered S3 method overwritten by 'jsonify':
method from
print.json jsonlite

• 已尝试更换R版本、重装R、更新相关包，问题仍未解决。

复现代码 #

library(mapdeck)
set_token(TOKEN) 
mapdeck() %>%
  add_path(
    data = roads
    , stroke_colour = "RIGHT_LOC"  # 注释掉此行即可正常运行
  )

解决思路 #

• 检查颜色列数据类型：mapdeck的颜色参数要求列是字符型（颜色名称/十六进制）或数值型，若RIGHT_LOC是因子类型，先转成字符型：roads$RIGHT_LOC <- as.character(roads$RIGHT_LOC)
• 明确指定颜色映射：手动定义颜色映射规则，避免自动解析出错，比如：stroke_colour = mapdeck::scale_colour(variable = "RIGHT_LOC", palette = "viridis")
• 测试简化数据集：取roads前10行小数据运行，排除大数据量引发的内存或解析问题
• 降级jsonify包：警告提示jsonify覆盖了jsonlite的方法，尝试安装旧版本jsonify（如1.2.1），避免方法冲突
• 验证sf对象有效性：若roads是sf对象，运行sf::st_is_valid(roads)检查几何数据是否存在错误，无效几何可能在颜色映射时触发崩溃
• 脱离RStudio运行：打开纯R终端执行代码，排除RStudio交互或渲染层面的问题
