[R-pkg-devel] Undeclared packages ... in Rd xrefs

[Ulrike Grömping]

Dear package developeRs,

under the Fedora clang checks, I find the note

"Undeclared packages ‘FrF2’, ‘DoE.wrapper’, ‘sfsmisc’, ‘DoE.MIParray’, 
‘planor’ in Rd xrefs"

for my package DoE.base. I understand that package planor has been 
archived from CRAN; I don't understand what is wrong with the other 
xrefs; only the R-Devel Fedora clang flavor seems to complain, and I did 
not find an explanation in the section on cross references in Writing R 
Extensions. Can someone explain the meaning of this note?

Thanks and regards,
Ulrike
