我试图在r中编写一个代码,通过导出和分析推文进行情绪分析,以下代码应该清理推文调用情绪包进行评分并返回结果,此代码已被引用在许多科技博客中,代码如下:

score.sentiment = function(sentences , pos.words, neg.words , progress='none')
{
 require(plyr)
 require(stringr)
 scores = laply(sentences,function(sentence,pos.words,neg.words)
 {
     sentence =gsub('[[:punct:]]','',sentence)
     sentence =gsub('[[:cntrl]]','',sentence)
     sentence =gsub('\\d+','',sentence)
     sentence=tolower(sentence)
     word.list=str_split(sentence,'\\s+')
     words=unlist(word.list)
     pos.matches=match(words,pos.words)
     neg.matches=match(words,neg.words)
     score=sum(pos.matches)-sum(neg.matches)
     return(score)
 },pos.words,neg.words,.progress=.progress)
 scores.df=data.frame(scores=scores,text=sentences)
 return(scores.df)
}  

但是我继续收到以下错误:

score.sentiment出错(Datasetgaza $ text,pos.words,neg.words,.progress =" text"):   未使用的参数(.progress =" text")

通过的论点是:  gaza.scores = score.sentiment(Datasetgaza $文本,pos.words,neg.words,.progress ='文本&#39)

非常感谢任何有关代码的帮助

你错过了一个'。'在进步面前。 确定这会有所帮助。

    score.sentiment = function(sentences , pos.words, neg.words , .progress='none')
{
 require(plyr)
 require(stringr)
 scores = laply(sentences,function(sentence,pos.words,neg.words)
 {
     sentence =gsub('[[:punct:]]','',sentence)
     sentence =gsub('[[:cntrl]]','',sentence)
     sentence =gsub('\\d+','',sentence)
     sentence=tolower(sentence)
     word.list=str_split(sentence,'\\s+')
     words=unlist(word.list)
     pos.matches=match(words,pos.words)
     neg.matches=match(words,neg.words)
     score=sum(pos.matches)-sum(neg.matches)
     return(score)
 },pos.words,neg.words,.progress=.progress)
 scores.df=data.frame(scores=scores,text=sentences)
 return(scores.df)
}
