[R] Error on Text Mining for WordCloud

[Boris Steipe]

That looks to me like a rather basic misunderstanding of how R syntax works. You might want to have a look at the documentation of as.character(), and read about its return value. Then note that you are not assigning the return value to anything. 

To wit:

a <- 5
mode(a)

as.character(a)
mode(a) # simply calling as.character() does not change a!

a <- as.character(a)
mode(a)  # there we go.
