hi brennan, survey design objects can be subsetted with the same subset()
syntax as data.frame objects, so following jeff's advice maybe you want
svyglm( formula , design = subset( surveydesign , variable %in% c( 'value
a' , 'value b' ) ) )
for some examples of how to construct a survey design wi
This seems like a fundamental misunderstanding on your part of how operators,
and in particular logical expressions, work in computer languages. Consider
some examples:
1+2 has a numeric answer because 1 and 2 are both numeric.
1+"a" has at the very least not a numeric answer because the values
I am aware that it is possible to specify a subset with a single
logical operator when constructing a model, such as:
svyglm(formula, design=data, subset=variable=="value").
What I can't figure out is how to specify a subset with two or more
logical operators:
svyglm(formula, design=data, subset=v
