如何使用R中的streamR包跟踪带有特殊字符的单词? [英] How to track words with special characters using streamR package in R?

问题描述

我正在使用 streamR 包来流式传输一些推文，但它不适用于一些葡萄牙语单词，例如policia"、médico"、audiência"和politica"等.如果我改用policia"，它只会显示包含西班牙语policia"的推文，葡萄牙语不显示policia".

I am using streamR package to stream some tweets but It's not working with some portuguese words like "polícia", "médico", "audiência" and "política", etc. If I use "policia" instead, It only shows tweets containing "policia", in spanish, It doesn't show "polícia" in portuguese.

我使用的是 R 3.1、Windows 7、streamR 0.2.1.这是一段代码:

I'm under R 3.1, Windows 7, streamR 0.2.1. Here is the piece of code:

> filterStream(file="acento.json", track="polícia", timeout=60, oauth=twitCred)
Capturing tweets...
Connection to Twitter stream was closed after 61 seconds with up to 4 tweets downloaded.
> df <- parseTweets("acento.json")
Error in readLines(tweets, encoding = "UTF-8") : 
  5 arguments passed to .Internal(readLines) which requires 6

这条显示找到 4 条推文的消息看起来像是一条默认消息，因为生成的 json 文件永远不会超过 1kb.

This message showing that 4 tweets were found looks like a default message, because the json file generated never exceeds 1kb.

> filterStream(file="acento1.json", track="política", timeout=60, oauth=twitCred)
Capturing tweets...
Connection to Twitter stream was closed after 62 seconds with up to 4 tweets downloaded.
> df <- parseTweets("acento1.json")
Error in readLines(tweets, encoding = "UTF-8") : 
  5 arguments passed to .Internal(readLines) which requires 6

有人能告诉我如何处理这个问题吗?

Could someone please give me a hint of how to deal with this?

推荐答案

为 policia 试试这个:

filterStream(file="acento.json", track="pol\u00edcia", timeout=30, oauth= twitCred)
