Dear R-devel list members, Under the development version of R (2.6.0), I notice that my sem package produces the following warning: checking Rd files ... WARNING Rd files with unknown encoding: residuals.Rd I wonder what the warning means. As far as I can see, residuals.Rd is similar to the other .Rd files in the package. At least for the time being, I won't reproduce residuals.Rd here in the interest of brevity. Any help would be appreciated.

'Writing R Extensions' tells you that for files that are not entirely ASCII you need to declare the encoding: I presume you want \encoding{latin1}. You might also want to think about the N^{*} in the latex version and the N in the not-so-plain text version. -- Brian D.
