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.
You have in the \details of that file:
(s_{ij} - c_{ij})/[(c_{ii}c_{jj} - c_{ij}²)/N]^{1/2}}
and that superscript 2 (which will probably come out in your mailer but
not for all readers) is not ASCII. '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.
