[R] issue running svyglm after subsetting: NA/NaN/Inf in foreign function call (arg 1)

[Anthony Damico]

hi, that error happens before svyglm because the second parameter isn't a
logical test?  run `subset(rclus1, as.factor(stype=="E"))` and you'll see
the same error..  if you remove the "as.factor" `subset(rclus1,
(stype=="E"))`  then the svyglm simply fails to converge but i think that's
just too many variables without enough sample?  thanks
