Hi,
it seems not possible to susbset a svydesign object (DBI svydesign) and use
variables to make the subset expression
uff<-c("14","15")
for (i in 1:length(uff))
{
subpnad<-subset(pnad, uf==uff[i] & v0302=='4')
}
the error is the following
Error in sqliteSendQuery(con, statement, bind.data) :
error in statement: no such column: uff
I have tried to use eval to make the expression without sucess, then
for (i in 1:length(uff))
{
expr<-eval(paste0("uf==",uff[i]," & v0302=='4'))
subpnad<-subset(pnad, expr)
}
complains that "no such column: expr" exists.
how to solve that?
Thanks!
