Description
Adds new variables/columns in dataframe to represent numeric regressors for a factor.
Factors are coded using their currently defined contrast codes.
This function is useful for control of a factor covariate when graphing
and ignoring this factor and/or other lower-level control variables.
For this purpose, POC coding will typically be set for factor prior to using lm.codeRegressor
Usage
1
varRegressors(Data, VarName, RegressorNames = NULL)
Arguments
Data
The dataframe to add regressors
VarName
Character string name of variable to code regressor for
RegressorNames
Optional variable names for regressors.
Value
Returns original data frame (Data) with addition of new regressors.
