Dear Prof. Ripley: Thanks very much. I did as you suggested, which I'll outline here to make it easier for anyone else who might have a similar problem:
* Read the offending *.Rd file in R using 'readLines' * Applied 'iconv' to the character vector, following the last example in the help file. This translated all offending characters into a multi-character sequence starting with '<'. * Used 'regexpr' to find all occurrences of '<'. The latter identified other uses of '<' but produced a sufficiently short list that I was able to find the problems fairly easily. Thanks again. Spencer Graves p.s. And in the future, I will refer 'Rd' questions to 'R-devel', per your suggestion.
