svyciprop object

Hi,?I'd like to access to the different elements in a svyciprop object (to the confidence intervals in particular...). But none of the functions I know works.Thank you for your help !

grr <- svyciprop(~temp==bzz, dclus1)> grr? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?2.5% ? 97.5%temp == bzz 0.040719697 0.027622756 0.05965> attributes(grr)$names[1] "temp == bzz"

$var? ? ? ? ? ? ? ? ? ? ? ? as.numeric(temp == bzz)as.numeric(temp == bzz) ? ? ? 6.42377038236e-05
$ci? ? ? ? ? ?2.5% ? ? ? ? ? 97.5%?0.0276227559667 0.0596454643748?
$class[1] "svyciprop"

grr$ciErreur dans grr$ci : $ operator is invalid for atomic vectors> grr["ci"]<NA>?? NA?> ci(grr)Erreur : impossible de trouver la fonction "ci"
