Dear all,
When running function 'testQAReport()', which uses function
'buildVignettes()' to create a pdf-file I get the following error:
source("testQAReport.R")
testQAReport()
Error in .get_package_metadata(pkgdir) :
Files 'DESCRIPTION' and 'DESCRIPTION.in' are missing.
Since I did not get this error in earlier versions of R, could you please
tell me what may be the reason for this error?
Here is the code for "testQAReport.R":

This is the quality assessment report for the dataset '@DATASET@'. The
dataset consists of
@NUMTREES@ Affymetrix @CHIPTYPE@ arrays of type '@CHIPNAME@'. \\
This report was generated using function \Rfunction{xpsQAReport} of package
\xps. \\
The file "QC.end.Rnw" is as follows:
\section{Summary}
The current quality report for dataset '@DATASET@' displays the most
important quality plots, using the
default settings for most plots. Package \xps\ contains additional plots
which can be used for further
quality assessments. \\

Can you please tell me why function buildVignettes() of the tools package is
no longer able to convert this file into a pdf-file?
Thank you in advance.
