your answer is correct after checking some doc
but examples are rare
when i write in the description file
Depends: R (>= 2.3), quadprog, ade4, spdep
and in the namespcae file
useDynLib(quadprog)
useDynLib(spdep)
useDynLib(ade4)
importFrom("dist.dudi", "ade4")
importFrom("solve.QP", "quadprog")
importFrom("mstree", "ade4")
importFrom("neig2mat", "ade4")
importFrom("dist.dudi", "ade4")
importFrom("dudi.pca", "ade4")
importFrom("dudi.coa", "ade4")
importFrom("knearneigh", "spdep")
i obtain :
Namespace dependencies not required:
dist.dudi dudi.coa dudi.pca knearneigh mstree neig2mat solve.QP
if i delete the importFrom lines
i get an error about "loading / namespace not succesful" for svcr
i think the solution is not far but it is disturbing
thank for help
