Thanks for reporting. This is a bug in the removeWords() function in
tm version 0.5-1 available from CRAN:

Mark,
It looks like removeWords removed "the" in all instances except when
"the" was the first word in your text. Maybe there is a parameter that
needs to be set? I couldn't find anything on the help page.
Here's an example of what I am seeing using the "crude" dataset
#function re
Sam,
Thanks for the example. Removing stop words after the DocumentTermMatrix has
been created works fine if one is working with single words, but what if one
is creating a dtm of possible combinations of words? Wouldn't one want to
remove them from the corpus?

I'm not sure what's wrong with your approach, but this seems to strip
"the"
require(tm)
params <- list(minDocFreq = 1,
removeNumbers = TRUE,
stemming = TRUE,
stopwords = TRUE,
I am using code that previously worked to remove stopwords using package
"tm". Even manually adding "the" to the list does not work to remove "the".
This package has undergone extensive redevelopment with changes to the
function syntax, so perhaps I am just missing something.
