[Rd] about integration of a library into package creation

[Nicolas Turenne]

i follow your recommendation writing this :
in the description file
Depends: R (>= 2.3), quadprog, ade4, spdep
Imports: quadprog, ade4, spdep

in the namespace file
useDynLib(quadprog)
useDynLib(spdep)
useDynLib(ade4)
importFrom("ade4", "dist.dudi")
importFrom("quadprog", "solve.QP")
importFrom("ade4", "mstree")
importFrom("ade4", "neig2mat")
importFrom("ade4", "dist.dudi")
importFrom("ade4", "dudi.pca")
importFrom("ade4", "dudi.coa")
importFrom("spdep", "knearneigh")

and the result of compiling is :
  preparing package svcR for lazy loading
Erreur dans loadNamespace(ns, lib.loc) : le package 'quadprog' n'a pas 
d'espace de noms
Exécution arrêtée
make: *** [lazyload] Error 1
*** Installation of svcR failed ***

it says that quadprog has not a namespace
perhaps it is due to location of quadprog.dll
i have put it into inst/src directory

thank for help

Nicolas
