[問題類型]:
因為要做報告 想要試著做ptt textmining 照著陳嘉葳大大的步驟做結果碰到了一對問題
[軟體熟悉度]:
新手(第一次寫R，因為要寫報告才接觸的XD)
[問題敘述]:
1.無法安裝tmcn套件
安裝後會出現
* installing *source* package 'tmcn' ...
** libs
*** arch - i386

2.無法安裝Rwordseg
安裝會出現

3.執行程式碼出現Error in curl::curl_fetch_memory(url, handle = handle) :
Couldn't resolve host name 程式碼如下
4.求一個可以跟《用R進行中文 text Mining》做到相同效果的程式碼
[程式範例]:
data <- data[data!="webptt.com/m.aspx?n="]
setwd("C:\\Users\\家\\Desktop\\R Test\\新增資料夾")
doc.size <- length(data)
doc.list<-c()
for( k in 1:length(data)){
html <- content(GET(data[k],config=set_cookies("over18"="1")),
encoding="UTF-8")
doc <- xpathSApply(html, "//div[@id='main-content']", xmlValue)
if(length(as.character(doc))==1){
name <- strsplit(data[k], '/')[[1]][4]
write(doc, gsub('html', 'txt', name))
}
}
[環境敘述]:
R 3.2.5 x32
[關鍵字]:
