the same problem.
> reut21578 <- system.file("texts", "crude", package =
"tm")
> (r <- Corpus(DirSource(reut21578), readerControl = list(reader >
readReut21578XMLasPlain)))
A corpus with 20 text documents

> (r <- Corpus(DirSource(reut21578), readerControl = list(reader >
readReut21578XMLasPlain)))> >
> summary(r)

The metadata consists of 2 tag-value pairs and a data frame
Available tags are:
  create_date creator 
Available variables in the data frame are:
  MetaID 
> rec.matrix <- TermDocMatrix(r) 
Error: no se pudo encontrar la funci?n "TermDocMatrix"

Package tm does not have a function TermDocMatrix.
Where did you get the idea that it does?

There _is_ a function TermDocumentMatrix, however.
