R help - Jan 2010 - Invalid input error in tm package

Hello,

I am working on "tm" package.
I have 2 pdf files saved in the directory D:/Files
I issued the following commands (marked in red bold) for which I got some
errors and warnings (marked in bold)

*surgj <- Corpus(DirSource("D:/Files"), readerControl =
list(language "ansi"))*

*Warning messages:
1: In readLines(y, encoding = x$Encoding) :
  incomplete final line found on 'D:/Files/provmedsurgj00978-0005b.pdf'
2: In readLines(y, encoding = x$Encoding) :
  incomplete final line found on 'D:/Files/provmedsurgj00978-0007.pdf'*

*> inspect(surgj)*

*A corpus with 2 text documents

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

[[1]]
%PDF-1.3
Error: invalid input '%Åþë×' in 'utf8towcs'*

Could anybody help me to identify where I went wrong and what I need to do
to proceed further?

Thanks,
Shreyasee

Dear Shreyasee,

I had exactly the same error message. I converted the pdf-files into plain
textfiles and reran the command without any problems. I'm no expert but the
problem must be with the readability of the filetype.

Kind regards

Kutsal
