In inTextSummaryTable: Creation of in-Text Summary Table

Compute the interaction between variable(s), without propagating the missing values (if present in one of the variable) unlike the behaviour with interaction. This also ensure that the levels of the final interaction variables are ordered similarly as the levels of the input var (if present).

Description

Compute the interaction between variable(s), without propagating the missing values (if present in one of the variable) unlike the behaviour with interaction. This also ensure that the levels of the final interaction variables are ordered similarly as the levels of the input var (if present).

Usage

interactionCustom(data, var, varDataLevels = NULL)

Arguments

data	Data.frame with data.
var	Character vector with variable(s) to consider.
varDataLevels	(optional) Data.frame with data to consider to define the levels of the variable. If not specified, only the combinations of variable(s) available in the data are retained.

Value

list with:

• 'x': factor with interaction between the input var

• 'dataLevels': data.frame with mapping between the var variable(s) and the new factor levels
