R tm package invalid input in 'utf8towcs'

Question

I\'m trying to use the tm package in R to perform some text analysis. I tied the following:

require(tm)
dataSet <- Corpus(DirSource(\'tmp/\'))
dataSet <         


        

Answer 1

I think it is clear by now that the problem is because of the emojis that tolower is not able to understand

#to remove emojis
dataSet <- iconv(dataSet, 'UTF-8', 'ASCII')
