Remove the non-ASCII characters, or declare an encoding.

You didn't tell us your OS -- one good way I find on Linux to spot such characters is to use 'less 'in the C locale. Another is something like (in R)

foo <- readLines("foo.Rd")
foo2 <- iconv(foo, "", "ASCII", sub="byte") foo2[foo2 != foo]

which should show the line(s) concerned with non-ASCII characters highlighted as <xx>.
