wtd_tab: Create weighted frequency table with multiple row variables

In alexdulin/MCmrp: Morning Consult's tools for Multilevel Regression and Poststratification

Description

Generate combined weighted frequency tables for multiple x-axis variables, both for oneway and two-way tables.

Usage

wtd_tab(data, xvars, yvar = NULL, weights = NULL,
  normwt = getOption("MC.normwt"), nowt.show = getOption("MC.nowt.show"),
  dem.table = FALSE, top.table = FALSE)

Arguments

data	a data frame containing the variables to use in the table.
xvars	character: vector of variable names in data for x-axis rows.
yvar	character: response variable for the y-axis in a two-way table.
weights	character: column name in data containing the sample weights.
normwt	logical: if TRUE, normalize weights so that the total weighted count is the same as the unweighted one. Defaults to options(MC.normwt).
nowt.show	logical: if TRUE, include unweighted registered voter statistics at the end of the table. Defaults to options(MC.nowt.show).
dem.table	logical: if TRUE, creates data for a demographic summary table.
top.table	logical: if TRUE, creates data for a topline table.

Details

An updated version of the wtd_table function from the questionr package with the added functionality of taking multiple vectors as the x argument. Additionally produces rownames for the resulting table using the levels of the variables passed to xvars and column names using the levels of the variable passed to yvar.

Value

If yvar is not provided, returns a weighted one-way frequency table of xvars. Otherwise, returns a weighted two-way frequency table of xvars and yvar.

Examples

# Regular two-way frequency table
wtab1 <- wtd_tab(data, listVars, vars[3], 'wts')
wtab1

# Demographic frequency table
wtab2 <- wtd_tab(data, listVars, NULL, 'wts', dem.table = TRUE)
wtab2

# Topline frequency table
wtab3 <- wtd_tab(data, vars, 'xdemAll', 'wts', top.table = TRUE)
wtab3
