Jeff,
Here is the solution:
myTerms <- c("prostatic", "adenocarcinoma", "grade")
inspect(DocumentTermMatrix(docs, list(dictionary = myTerms))) ## only returns
from first 10 docs in DTM
as.matrix(DocumentTermMatrix(docs, list(dictionary = myTerms))) ## returns
from all docs in the DTM

Subject: Re: [R] PROBLEM USING DICTIONARY WITH TM PACKAGE
Considering the deafening silence after three repeats, one explanation could be
that you are asking the wrong group of people. It is also possible that your
failure to follow the Posting Guide with regard to using plain text email and a
reproducible example [1][2] means that readers who are not experts do not feel
inclined to follow along with you and help you think of solutions. Keep in mind
that supporting contributed packages like tm is technically not on topic here,
though people often do feel the urge to help solve problems with them anyway.
With regard to asking the wrong group of people I would suggest asking the
maintainer of the tm package what they recommend. See the help for the
maintainer function or read the CRAN Web page for that package.
