Produces a person-level dataset with question-level dataset. This will only use the variables necessary for the model, thus its name "slim". Therefore, is model dependent.

cces_join_slim(
ccq_df,
ccc_df,
cd_df,
formula,
coerce_to_char = TRUE,
keep_vars = NULL,
subset_dist = NA
)

## Arguments

ccq_df dataframe of outcomes, taken from get_cces_question. We currently assume the name for the outcome is named "response", although this can be modified with the y_named_as argument dataframe of covariates, currently taken only from the cumulative common content. It should have passed ccc_std_demographics to be compatible with ACS. dataframe of district-level predictors, see cd_info_2018 for a sample. Currently, we join this to the rest of the data on the column called "cd" and "year". the model formula used to fit the multilevel regression model. Should be of the form y ~ x1 + x2 + (1|x3) where y is a binary variable and only categorical variables should be used in the random effects notation. Whether to coerce the case identifier to character class, this enables the join. Variables that will be kept as a cell variable, regardless of whether it is specified in a formula. Input as character vector. a character for the geography of cd to subset

## Examples

 if (FALSE) {
# need data/input/cces/cces_2018.rds to run this
ccq_tcja <- get_cces_question("CC18_326", "2018", "TCJA")

cces_join_slim(ccq_df = ccq_tcja,
ccc_df = filter(ccc_samp, year == 2018),
cd_df = cd_info_2018,
formula = "response ~ age + educ + (1|cd)")

# alternative - cd and state not in the formula, but cells follow this
cces_join_slim(ccq_df = ccq_tcja,
ccc_df = filter(ccc_samp, year == 2018),
cd_df = cd_info_2018,
keep_vars = c("st", "cd"),
formula = "response ~ age + educ")
