[R] speed issue: gsub on large data frame

Good idea! 

I'm trying your approach right now, but I am wondering if using str_split
(package: 'stringr') or strsplit is the right way to go in terms of speed? I
ran str_split over the text column of the data frame and it's processing for
2 hours now..? 

I did: 
splittedStrings<-str_split(dataframe$text, " ")

The $text column already contains cleaned text, so no double blanks etc or
unnecessary symbols. Just full words.
