wtd.table: Weighted one-way and two-way frequency tables.

In questionr: Functions to Make Surveys Processing Easier

Weighted one-way and two-way frequency tables.

Description

Generate weighted frequency tables, both for one-way and two-way tables.

Usage

wtd.table(
  x,
  y = NULL,
  weights = NULL,
  digits = 3,
  normwt = FALSE,
  useNA = c("no", "ifany", "always"),
  na.rm = TRUE,
  na.show = FALSE,
  exclude = NULL
)

Arguments

x	a vector
y	another optional vector for a two-way frequency table. Must be the same length as x
weights	vector of weights, must be the same length as x
digits	Number of significant digits.
normwt	if TRUE, normalize weights so that the total weighted count is the same as the unweighted one
useNA	wether to include NA values in the table
na.rm	(deprecated) if TRUE, remove NA values before computation
na.show	(deprecated) if TRUE, show NA count in table output
exclude	values to remove from x and y. To exclude NA, use na.rm argument.

Details

If weights is not provided, an uniform weghting is used.

If some weights are missing ('NA'), they are converted to zero. In case of missing weights with 'normwt=TRUE', the observations with missing weights are still counted in the unweighted count. You have to filter them out before using this function if you don't want them to be taken into account when using 'normwt'.

Value

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