Construct a matrix of binary variables for calibration

Description

Construct a matrix of binary variables for calibration of sample weights according to known marginal population totals. The following methods are implemented:

  • calibVars.default(x)

  • calibVars.matrix(x)

  • calibVars.matrix(x)

  • calibVars.data.frame(x)
