Hello,
I'm trying to use the function svyglm in the library survey.
I create a data survey object:
data_svy<- svydesign(id=~PSU, strata=~sample_domain,
weights=~sample_weight, data=data, nest=TRUE)
and I try to use svyglm() with little success:
R<-svyglm(data_svy[,4]~(data_svy[,iCol]==listModality[[iVar]]
[iMod]),design=data_svy, family=binomial(link="logit")
Error in svyglm.survey.design(data_svy[, 4] ~ (data_svy[, iCol] ==
listModality[[iVar]][iMod]), :
all variables must be in design= argument
Puzzlingly the following code works:
R<-glm(data[,4]~(data[,iCol]==listModality[[iVar]][iMod]),
family=binomial(link="logit")
Any help would be gratefully accepted.
Best,
Federico
