第一次在stackoverflow提问。
我正在尝试通过 lodown R 包遵循有关 PNS (Pesquisa Nacional de Saúde) 的示例（书中的说明http://asdfree.com/）。我严格按照代码进行操作，但不断收到错误消息。这是我从 R 与 sessionInfo() 一起获得的代码和输出错误消息。有办法获取数据吗？我不明白收到的错误消息。

好吧，已经有一段时间了，但我要回答我自己的问题。我尝试联系 lodown 的维护者，但没有成功。与此同时，发布了一个非常好的包来从 IBGE 获取 PNS 数据。如果有人对此感兴趣，该软件包称为“PNSIBGE”。
install.packages("PNSIBGE")
你成功加载2013年的数据了吗？我只能加载 2019 年的 Wave，就像 2013 年一样，我得到“std::bad_alloc”
