Sunil Kappal demonstrates how to use Deducer, a GUI for R, to perform a simple linear regression:
Selecting the variables in the Deducer GUI:
Outcome variable: Y, or the dependent variable, should be put on this list
As numeric: Independent variables that should be treated as covariates should be put in this section. Deducer automatically converts a factor into a numeric variable, so make sure that the order of the factor level is correct
As factor: Categorically independent variables (language, ethnicity, etc.).
Weights: This option allows the users to apply sampling weights to the regression model.
Subset: Helps to define if the analysis needs to be done within a subset of the whole dataset.
Deducer is open source and looks like a pretty decent way of seeing what’s available to you in R.
