svyrmpg(formula, design, ...)

## S3 method for class 'survey.design'
svyrmpg(
  formula,
  design,
  quantiles = 0.5,
  percent = 0.6,
  na.rm = FALSE,
  thresh = FALSE,
  poor_median = FALSE,
  ...
)

## S3 method for class 'svyrep.design'
svyrmpg(
  formula,
  design,
  quantiles = 0.5,
  percent = 0.6,
  na.rm = FALSE,
  thresh = FALSE,
  poor_median = FALSE,
  ...
)

## S3 method for class 'DBIsvydesign'
svyrmpg(formula, design, ...)

Arguments

formula

a formula specifying the income variable

design

a design object of class survey.design or class svyrep.design from the survey library.

...

future expansion

quantiles

income quantile, usually .5 (median)

percent

fraction of the quantile, usually .60

na.rm

Should cases with missing values be dropped?

thresh

return the poverty poverty threshold

poor_median

return the median income of poor people

Details

you must run the convey_prep function on your survey design object immediately after creating it with the svydesign or svrepdesign function.

Value

Object of class "cvystat", which are vectors with a "var" attribute giving the variance and a "statistic" attribute giving the name of the statistic.
