cbind: Combine mimids and wimids Objects by Columns

Description

This function combines a mimids or wimids object columnwise with additional datasets or variables. Typically these would be variables not included in the original multiple imputation and therefore absent in the mimids or wimids object. with() can then be used on the output to run models with the added variables.

Usage

cbind(..., deparse.level = 1)
# S3 method for mimids
cbind(..., deparse.level = 1)
# S3 method for wimids
cbind(..., deparse.level = 1)

Value

An object with the same class as the first input object with the additional datasets or variables added to the components.

Arguments

...

Objects to combine columnwise. The first argument should be a mimids or wimids object. Additional data.frames, matrixes, factors, or vectors can be supplied. These can be given as named arguments.

deparse.level

Ignored.
