So let's backtrack. It so happens that I had just used read.dcf in the
context of a package. So let's try something simple:
R> read.dcf(system.file("DESCRIPTION", package="lattice"), "Package")
Package
[1,] "lattice"
R>
That works on my testing system just fine, in the running R session or on the
cmdline:
e...@ron:~$ r -p -e'read.dcf(system.file("DESCRIPTION", package="lattice"),
"Package")'
Package
[1,] "lattice"
e...@ron:~$
