我在语料库的文字说明中有很多网址链接。在使用tm_map函数应用标点符号后，它正在形成一个非常大的单词。所以，我想完全从我的文本文档中删除这些网址。
我已将csv文件加载为下面的示例。我应用了tm_map方法来删除puntuation，停止单词如下：
ques<-read.csv("datasets\\data100_.csv")
ques1<-paste(ques$content,collapse = "")
ques1<-iconv(ques1, "latin1", "ASCII", sub="")
ques1
corpus<-Corpus(VectorSource(ques1))
inspect(corpus)
corpus<-tm_map(corpus,tolower)
corpus<-tm_map(corpus,removePunctuation)
corpus<-tm_map(corpus,removeNumbers)
corpus<-tm_map(corpus,removeWords,stopwords('english'))
corpus<-tm_map(corpus,stripWhitespace)
corpus<-tm_map(corpus,trim)
corpus<-tm_map(corpus,PlainTextDocument)
我的示例文件data100_.csv如下所示：

"thumbslinger",2015-07-08,"Since it's now 2015 and all I find on this is from 2008/2011, I'm hoping some solid ideas have arrived for this.,We are hosting our actual site both the dev and the live site. I'm not an IT guy and in the past, this stage was all done so I logged on to the dev.xyz.com, made changes then ssh-d into dev.xyz.com and ran a script somebody else had made. Renamed a settings.php file and was done.,We had a dev server and a live server but two different databases on the live server. We also had two separate settings.php files; abc.settings.php and 123.settings.php each which pointed to one of two different databases; abc or 123.,That script:,1. dumped the database of dev.xyz.com,2. checked the settings.php file to see which of the two databases was actually in use, then,3. imported the previously dumped database into the other database on the live server (but not in use),4. synced.,Then, all I did was to renamed the appropriate settings.php file. So if the settings.php file was originally pointing to the ""abc"" database, I'd rename 123.settings.php to settings.php. (As that database would have had the lates dev db imported into it). Had the original (live) settings.php been pointing to the ""123"" database, then I'd rename the abc.settings.php to settings.php,But, I don't have that script. So I'm looking for the ways/means to do this. Is it using sqldump? Backing up is easy and can be done in a myriad of ways but I'm talking about how do I make the connection in 'what kind of script' between a dev server and a live server?,I'd like to dump the db, import it to the live server and be done.
